Windows 7 has swapped my drive paths with my boot drive and sec. drive

Question: Windows 7 has swapped my drive paths with my boot drive and sec. drive

I have just finished a pc build with a SSD to be used as the boot/OS drive and a secondary 2 HDD setup in raid 0 for storage.

First I started with the SSD only and installed win7, applied all the updates etc. At this point the system has rebooted at least half a dozen times with no issue.
Next I set up the 2 HDD in raid 0, initialized it with disk manager and everything is looking good. But as soon as I reboot the system, upon startup the system can't find a os. Using the windows install disc, I go into the recovery console and discover that the boot drive which was C:\ is now E:\ and the storage drive which was E:\ is now C:\.
The os files on the boot drive seem to be all there. It's just in the wrong drive path. Using the recovery console I switched back the drives to their proper places, but then on startup I got the error 'bootmgr is missing' at this point I gave up, nuked the drives and started from scratch only to get thing again once I initialized the HDD and rebooted.
I am sure I have overlooked some stupid detail somewhere. Can anyone help me figure out where I went wrong?

Preferred Solution: Windows 7 has swapped my drive paths with my boot drive and sec. drive

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Windows 7 has swapped my drive paths with my boot drive and sec. drive

My first thought with a new build is settings in the BIOS, many times something has to be changed.

My original WD hard drive was showing signs of instability, so I cloned it (using Norton Ghost) to a larger WD drive, setting the new drive to "boot" within Ghost, and removed the original drive.

When I boot up with the new drive, WinXP goes past the black XP toolbar screen to the blue icon splash screen and hangs. It doesn't freeze (you can still use your mouse) but it never displays the Users fields that let you log in. The same exact thing happens if you boot in safe mode. Registry problem? Appreciate any troubleshooting suggestions ...

More info: on doing some reading, I found this was a common problem with cloned drives. Someone in another thread suggested the problem was that Windows expected a C letter drive for example when the clone was assigned a D, so it couldn't tell which disk to load. They suggested using a FIXMBR command from the recovery console and rebooting, which I tried, but it had no effect unfortunately.

Greetings, all. I have an older Z60 that I'm trying to keep running for my daughter. The original 80G Hitachi hard drive finally crashed beyond recovery, so I replaced it with the hard drive out of a Lenovo 3000 C200 that was on the sidelines with a broken screen. I know the 'new' hard drive works fine, because I was able to run the 3000 with an external monitor and do all the Win upgrades and such last night. However, it's not exactly plug-and-play, as my Z60 won't boot from the newly-installed drive. I know it's finding and reading it - if I run ThinkAdvantage to start, it will find the drive, knows the drive name and capacity, can display file contents, etc. I tried booting from a Win CD, and it found the drive and partition (properly named) and the operating system intact, and balked at re-installing the operating system in the same partition. At this point, I'm stuck. I can reformat the drive if necessary, but would prefer to convince the system to boot properly from it. I don't think I messed up anything during the install (although I did take the cover completely off, as I was thinking of raiding the RAM chips). The original HD had two rubber bumpers on the sides of the drive, which didn't seem to want to fit on the replacement drive, although the form factors are identical. Any suggestions or ideas?  Thanks in advance!

Answer:Swapped hard drive won't boot

It is unlikely that you'll get a hdd to boot properly from a different machine. I would image the disk (you said it worked in the old machine) then wipe it and install it in the "new" machine and do a clean install.

OK, i got a strange one fellas. My partition drive letters get swapped in windows 7, although the information on the partition doesn't get affected. I got dual OS, xp and 7.

Answer:Drive letters get swapped in windows 7?!

Windows will call whatever the boot partition is the C drive. If you are running XP, the XP partition will be C, and if you are running 7, the 7 partition will be C.

I got a 120GB IDE drive to replace my old 20 GB drive. The old 20GB didnt have the operating system, ihave another 40 GB drive that has that installed but the 20GB is the primary drive. After i ghosted it i made sure that the 120GB was the master to the 40GB slave as it was in the first setup by just setting them as cable select, but now when i start up i get an error that says sinc there were hardware changes i need to "check boot path and disk hardware" because it cannot seem to boot. What should i do? i know the windows installation is there i just think the computer needs to be guided to it.

Answer:Ghosted/Swapped out drive, now windows not booting

Your boot drive should be set as master and your second drive set as slave. Also go into BIOS and make sure that both drives are recognized and the boot order is set properly.

I have a drive that has a lot of information on it that I need. A user left our company and all of his files are on this drive. I was handed it and asked to build a VM with all his information on it. When I plug the drive in it loads the drivers and shows
up just fine in Computer Management (shown below), but not in Computer. So I think, ok, I'll just add a drive letter but that option is greyed out and won't let me. The disk is initialized and appears to be healthy. I have gone to device manager and made sure
there were no problems there as well. It was also an external drive so I removed it and made it an internal drive on my machine but got the same results. It shows up in BIOS but obviously can't boot off of it since it is not an OS drive.
Deleting/formatting the drive is not an option. Is there a way to get this drive accessible without that? Deleting it is the exact opposite of what I want done here. 

Answer:Change Drive Letter and Paths... greyed out. Can't assign drive letter.

That looks like a mac formatted drive, that's why it wont work on your PC. Try installing Paragon HFS+ for Windows.

I've got an truecrypt partition with what we'll call some unflattering files. Nothing illegal or immoral, but nothing you want girlfriends or family members to find either.

I've got recently used files and all that turned off, but there's one place they're still popping up. If I open the run menu and type the letter "r," I'm greeted with a list of file paths whose existence I'd prefer Windows not advertise in any way ("R:" is where I mount the tc volume.)

My assumption is that it's related to Windows indexing, but none of the elements to manage indexing options that my google queries are suggesting seem to exist on my PC, so I'm guessing they only apply to Windows 10 Pro? At this point I'd settle for deleting the index entirely and disabling it, assuming the index is actually the problem. In any event, pic related.

Edit: So I've disabled the Windows Search service and deleted the Windows.edb file, which I understand is the index. Rebooted, and it's still showing up. I bounced over to my admin account, and it's not happening there. So it's on a per-user basis. Presumably in one of the AppData directories.

Edit2: Solved the problem by disabling autocomplete and deleted autocomplete history in the Content tab in Internet Explorer settings. Ridiculous.

I am trying to reinstall windows 8 on my desktop and did a reset from the system in windows, which worked it got rid of the virus.  But to make sure everything is really gone what I really want to do is clean the hard drive by doing a complete wipe
and reinstall and new copy of windows 8 that I have which contains a product key I have.  Back in 2011 I bought the computer and windows 8 failed (it kept saying it needed to be activated, we tried to enter the product key, didn't work, after several
months of issues with our retailer and Computer manufacturer found out it had to be reinstalled remotely by Microsoft so as of now I have Windows 8 on my desktop but do not have a product key.  So I purchased a copy of Windows 8 with a product
key but can't install it.
The problem is my computer does not boot first from the CD drive then the hard drive.  I can't find where to change this. I tried to go to the BIOS to change it but there is no prompt to select the CD drive.  if anyone has any suggestions
I would appreciate any help I can get.  I have a screen shot of the BIOS but it is too large to post.

Hi, I installed Windows 7 on a second hard drive (WD 500GB c) to create a dual boot with Vista (OS d). This has been working great and I have fully transferred over to Windows 7.

Now I want to remove the Vista drive (OS d) and format it to use for data only or in future purchase a larger capacity hd for data. I think my MBR is on the Vista drive so how can I do this safely and easily?

I have attached a screenshot from disc manager.

Answer:Removing Vista drive from a dual boot with Windows 7 on seperate drive

Unplug Disk 0 , and then run Startup Repair - Run 3 Separate Times . It will add the Windows 7 boot files in the WD 500 GB disk 1.

(But if you want to make the boot files in a separate partition (which is a usual situation with a clean install), you may see System Reserved : Create Using Disk Management .)

Now you are able to Boot up windows 7 directly .... so you may easily format the Vista disk, if you want, either using the option three of the tutorial Partition Wizard : Use the Bootable CD , or Disk - Clean and Clean All with Diskpart Command or SSD / HDD : Optimize for Windows Reinstallation .

Hope it helps .

EDIT : If you dont want to format the vista drive, you will need to delete the windows 7 boot entry from it . Download and install EasyBCD , Click on the "Edit Boot Menu" button and Click on delete , and save .
Now , you can use the either OS using the boot menu key of your computer, selecting which disk is to boo up during start up the computer.

OK--here's the situation. I am trying to copy and old drive onto a new computer--the new one has two SATA drives with one having the OS. I want to copy the person's old main drive (a PATA) to the new computer but no matter where I put it--the BIOS wants to recognize it as the master drive. I have tried it as a slave. I think the problem is the PATA IDE controllers are checked first and of course as soon as the drive is recognized, it wants to boot from it.

Question: Drive Swapped

I came home to see the message "BOOT DISK FAILED". Shut down the unit and rebooted, got into windows XP professional but all the program files and desktop items were missing.

I back up reguraly and began replacing missing items when I realized my D Drive (250 Meg Maxtor) had now become my C Dive. And my C Drive was now my D.

After going through the BIOS and assuring everything was identified correctly, I rebooted, and still got my Old D as my C Drive.

I corrected the problem by unplugging the Old D (slave) and rebooting with 1 Drive which was recognized as my C and everything once lost was now back.

After shutting down, re-plugging in the D Drive and re-booting, everything was back where it was.

So, what causes XP to switch drives?


Answer:Drive Swapped

A power surge (voltage spike) could have screwed it up. If it happens again use Manage on the My Computer right click drop down menu to correct the letter assignments.

Hi guys,

So I'm no longer able to boot into my main drive, but all my files and folders on that drive still look intact. I honestly don't know what went wrong or if there is any way to fix this other than reinstalling Windows. Tried startup repair on my Windows 10 installation USB, that failed. I'll explain every step I took.

I should first mention I just built this PC and I bought an M.2 SSD to use as my main drive, but I also installed my SATA SSD from my old PC. After installing Windows 10 on my M.2 drive I was able to select which drive I wanted to boot into every time I started my PC. I didn't format that SATA SSD until just before when I went to install another copy of Windows on it. Here's what happened.

I booted into my installation USB. My main drive (the M.2 SSD) was called drive 2 and my other drive (the SATA SSD) was called drive 0. I formatted then deleted the main partition of drive 0, then deleted all the smaller partitions of reserved space so the drive only had one volume of unallocated space. Then I selected that unallocated space and selected new, which recreated all the smaller partitions. I then selected the main partition of drive 0 and pressed next, which installed it on that drive. It installed successfully, but I first noticed something was odd when I didn't see the boot manager after I restarted my computer, it just automatically boots to the new copy of Windows. I noticed in my BIOS the boot order has the boot manager for my SATA SSD as the fi... Read more

Answer:Can't boot into main drive after installing Windows on another drive

When you installed Windows onto the M.2 SSD, you still had the SATA SSD installed. Windows setup found the EFI System Partition on the SATA SSD and put the boot files there instead of the M.2 SSD. That is why we recommend that you have only the drive connected that you want to install Windows on until the computer is successfully booting from it, then connect your other drives.

Now, if you don't want to do a reinstall that way, you will have to make room on the M.2 SSD for an EFI System Partition formatted as FAT32 (250 - 500 MB in size) and manually create the boot files on it.

This problem all stems from the fact I want to change a drive letter of a drive that is NOT my boot drive, which should be quite easy. I reinstalled Windows last night on the same drive it was on before (C drive). Before installing, I detached all my other drives to avoid confusion. The install completed, I booted up, turned off again, and then reattached my 3 other drives. Two of the three drives complied with my wished to change their drive letter. The third, however, kicks me an error saying that it is a system drive and "Windows cannot modify the drive letter of your system volume or boot volume."

What have I done?

Answer:What is the difference between a windows Boot drive and a system drive?

Boot drive has boot loader & boot sectors on it.
System drive has windows on it.

If they aren't the same in your system, then it is probably because you installed windows when both disks were present in the system, and the one that became "BOOT" was the one that the BIOS returned first, and the one that is "SYSTEM" is the one that you picked to install windows on (and likely became C: but that may or may not be the case)

Since you installed with only one drive, it is also likely that one of the other drives HAS a valid boot sector on it already (possibly from a previous windows install) and is currently the 'first' drive the BIOS tries to boot, and thus the system uses that for the boot sector but ends up using another drive with the windows install. I would check into the bios/boot order stuff.

My primary HDD was failing so I backed it up and replaced it with a larger 1TB drive.  After reinstalling everything the new drive is displaying the same size as my old drive and the extra space available is unallocated.  I can allocate it as
a separate drive but I find that annoying and would prefer to just have my primary C: drive show up with all of the available space.  I formatted the extra space and made it available separately as drive G hoping that I could EXPAND drive C but that option

I am new and bad at computers, please take that into consideration.

I installed a new SSD and then mirrored my old HDD onto the SSD. I then made the SSD my Boot Drive in Disk Management. I am a little unclear about the ramifications.
First, does making the SSD my Boot Drive mean that my SSD is running Windows? If not, how can I confirm which drive is running Windows? If it is not the SSD, how do I make it be the SSD?
Second, once I am sure that it is my SSD running Windows and not my old HDD, can I delete all the Windows files from the old HDD? I would like to do this.
Third, is there any reason I should swap the names of my drives? Right now Drive C is my old HDD and I am booting from drive D, my SSD. I would prefer if new programs defaulted to being installed on my HDD, but does this make Windows updates, or anything else important, awkward.
Fourth, I notice that when I run computer games off my SSD now that none of my personal settings are retained - whereas if I run them off the HDD my personal settings are as they were before the mirror. Could someone explain this to me? If the SSD is a mirror of the HDD, then shouldn't personal settings in applications also be mirrored?

Here is a screen shot of my Disk Management. Drive C is my old HDD. Drive D is my new SSD. Drive E is storage.
Thank you!

Answer:New Boot Drive. Help Confirming Boot Drive is Running Windows.

D is booting Win7 as shown by the Boot label. The problem is that Win7 is designed to always be C if it is correctly installed from boot and not run from another OS, or if you select Auto when choosing drive letter for cloning or imaging. So you've stuck yourself with the letter D for Win7 if that's okay with you. You can clone it again and designate Auto so it correctly boots as C if you want.

The correct way to delete an OS is to delete or format its partition after moving any files off of it you want to save. In this case I would delete both the System Reserved and C partition after moving the data to a new data partition you shrink C to make. Later resize back into the deleted partition space using Partition Wizard Move/Resize Partition Video Help.

You should install Programs to the SSD to get best performance, leave the paging file on the SSD as well although if space gets tight you can set it to 2gb in size if it's taking more. You can copy your User folders to a new data partition on the HD and rightclick each to link to the related Win7 Library - Include a Folder - Windows 7 Forums which is the best way to access your data on the HDD.

I don't know why your settings aren't carried over, but settings are a corruption path into a new install anyway. In fact if you wanted the best possible install for a new SSD to take maximum advantage of its speed you should do a Clean Reinstall - Factory OEM Windows 7 which steps are the same for retail.

I'm working on my sister computer and put in a new hard drive. I imaged the drive in windows (using xp) and all seemed to go ok. I took the original out and now windows will book ok, but will hang on a screen that resembles the windows login screen, blue background with a windows xp logo on the right side. The mouse still works as well as the numlock lights, but it will go no futher. I've tried changing drive letters with the old drive installed, but somehow, i've fubar'd both and now both drives hang at this spot regardless of whether or not the other is plugged in as well. I have a feeling, from research i've done on the web, that windows is looking for system files on a drive letter that doesn't exist. The problem now is that i cannot boot into either install of windows, nor thier respective safe mode options. In safe mode, i get the same screen as i do when booting into normal mode. How do i get either one of these drives to boot? I know the data is still there and the data is fine, but I need to make windows boot. I've also tried using the recovery console to do a fixmbr and a fixboot, but neither helped (I didn't figure they would as the address different aspects of the boot than what i suspect to be the problem).

I've been scouring the internet for a solution to my trouble for some time now, and have found a lot of useful information here, but none quite relevant to my specific problem. I'll try and make this short and sweet, whilst posting as much relevant info as I can here.

My dilemma is this....I have an Intel dual-core CPU running Win7 Pro x64, and it runs great. chkdsk /r revealed 0 issues with the drive. I recently acquired a Core i3 machine, and want to drop my drive into it. Past experience tells me I should have 0 problems doing this, so long as I keep the hardware similar and CPU vendor the same. Both machines are Lenovo with Intel processors. When I plug my drive into the new i3 box, it loads the Windows splash screen and BSOD with "unmountable boot volume". Easy enough, I'll boot it off USB-SATA adapter, and bypass the SATA on the motherboard (no RAID on either PC) and let Windows detect all the hardware on the new PC first. Same result doing that too. OK, so I'll try booting off USB-SATA adapter on my original WORKING machine, but got the same result. I've tried the startup repair disc to no avail. It's like my drive will only boot off the onboard SATA on my working machine, and it IS a basic disc, not dynamic.

This is most unsatisfactory because it appears you have bootmgr on drive C and Windows 7 on drive D.However, you can change a registry key to point to drive D for future program installations: Click the Windows Orb (Start), type regedit, press Enter and navigate to registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion.

Hi, I am having serious problems with my desktop computer.

The problem started when the computer all of a sudden out of nowhere restarted one day while I was using it. From then on it would only log on to a temporary profile. After googling I concluded that it was a corrupt profile issue and I backed up all my files. But soon after doing this, the computer shut off again and would not reboot at all (I was using Windows 7).

So I decided to get a new SSD hard drive. I installed it into the desktop today and installed a Windows Vista(I couldn't find my Windows 7 CD). After this I tried to upgrade to Windows 8 (I purchased a downloadable .exe from online). However, when the computer would restart during the installation process, it always ended saying that the installation was unsuccessful. I did all the updates on Vista and got SP2, but Windows 8 would not install.

During my last attempt, the computer ended up giving me another Blue Screen and now Windows won't boot. I am so incredibly frustrated because I got a new hard drive and a new clean installation of Windows Vista.

Does this mean there is something wrong with my motherboard? I do not know much about computers and am clueless where to even begin tracking down the root issue. I am so overwhelmed. Please help with advice. Thank you so much.

Answer:Windows won't boot with old hard drive AND new SSD drive

First, make sure that your system is compatible with Windows 8 -- many Vista computers, and even some Win 7 computers are not.

Windows 8 system requirements - Microsoft Windows

If your system us compatible, rather than trying to upgrade to Win 8 from a Vista install, you may be able to just do a clean install of the Win 8 upgrade. I did this and it activated just fine, having already proven to MS that I had a legitimate copy of Win 7 and was eligible for the upgrade.

Answer:Configuring boot drive to windows 7 drive??

Your screenshot is nearly unreadable for some reason.

You need to remove the Active flag from all drives, convert Win7 from Logical to Primary so you can set it Active to recover the System MBR into it.

The tool to use is free Partition Wizard bootable CD: Boot PW, select 1 for screen res, rightclick on each partition currently marked Active and Modify>Set to Inactive, OK.

Then rightclick on Win7 partition to Modify>Convert to Primary, OK, then Modify>Set to Active, OK. Apply all steps.

Now enter BIOS setup to set WIn7 HD as first HD to boot (after DVD drive).

Finally boot the Win7 DVD Repair console or Repair CD, click through to Recovery Tools list to run Startup Repair up to 3 separate times with reboots until Win7 starts up. Startup Repair
System Repair Disc - Create

Keep XP as a data drive until you are sure you have all data off of it, then format it Logical for data using PW CD. I say this because Logical drives cannot be marked Active to confuse the Win7 Repair utility.

I have installed the OS (Windows XP pro). I have 2 hard disks, one is 160GB SATA and other is 250 GB PATA. The SATA hard disk is the boot hard disk. But sometimes, while working, the hard disk drive priority changes without any logical justification and the pc restarts and I get an NTLDR missing error. So I have to enter BIOS and change the hard disk priority again... after that the PC boots without problems!

Could anyone solve my problem?

Answer:Hard disk drive priority swapped

you might want to change the battery in you motherboard. This could be the problem.

after shrinking the D: partition, the drive letters and actual partition sequence on the drive changed - the C: (Vista) partition has switched places with the D: (Recovery) partition in Disk Management (D: is now in front of C

I first defragged the D: drive using JKDefrag and used its built in feature to move all the files to the end of that partition, so that after splitting D:, the blank portion would be next to the C: partition (so I could have it merge with C: )

how do I get the partitions back to their normal positions (in Disk Mgmt)?
and if I delete the D: partition, will it merges with C: and keep my Vista install harmed?

Answer:Drive Letters & Partition Contents Swapped

Hi, skye11, and welcome to the forums.

Before we continue, how large was this D partiton in the first place? Can you post a picture of it?

I suspect that the partiton being labeled previously as D: was in fact a partition inside of an extended partition, and if so, then any space that you reclaim from it will in fac be placed outside of the extended partition, thus making it appear between the two partitions....

Please post a picture using the Snipping tool (see How to Use the Snipping Tool in Vista for more details) so we can look at what you are looking at.

My PC, which is running XP SP3, has been playing up for the last month or so in that it has been reluctant to start up and has usually taken 2 or 3 attempts to get it past the mother board splash screen and into proper boot up. Yesterday, after several attempts at came up with a black screen and the words ?Boot disk failure, Insert system disk and press enter?
I put a system disk in which then gave me 3 options, install windows, repair windows or exit. Not being really sure that I wanted to do either of the first 2 I opted for install windows just to see where it took me. I showed that the drive letters of the 3 HDDs in the machine had changed drive letters and that the C drive was now D which would explain why it thought there was a boot disk failure. Bearing in mind the fact that the machine won?t start is there any way I can reassign the correct drive letters?
I did try Acronis boot disk which gave me the option to check the system which confirmed that the drive letters had been switched around.

Answer:PC Won't start, HDDs have swapped drive letters

If you are using Acronis can't you just use your last back up to sort it?

So when I re-installed XP back in the day, it assigned my second drive as J: instead of D:

So I switched the letter to D:, worked just fine up until this morning when I had to re-install some updated logitech software. It says that it cannot install to the J: drive. I checked the install path and it was pointing at the C: drive (that's fine) and when it starts extracting - it goes to J:

How can I make sure that J: doesn't show up and that I can install files again?

Please, and thankyou

When in Disc Management it is there ok but with no drive letter. Right click reveals drop down box but everything is Greyed out.

To initialize new disksIn Disk Management, right-click the disk you want to initialize, and then click Initialize Disk.
In the Initialize Disk dialog box, select the disk(s) to initialize. You can select whether to use the master boot record (MBR) or GUID partition table (GPT) partition style.
Note The disk is initialized as a basic disk.

Additional considerations
New disks appear as Not Initialized. Before you can use a disk, you must first initialize it. If you start Disk Management after adding a disk, the Initialize Disk Wizard appears so you can initialize the disk.

I had two laptops, both HP. One had Intel processor the other AMD. The AMD machine was running Windows 7 Home Premium 64 bit and the Intel machine was running Windows 7 Professional 32bit.

It all went fine with one exception............

I can't adjust the screen resolution to fill the entire screen. Device manager shows the yellow alert on the Mobile Intel 965 Chipset Family (Microsoft Corporation - WDDM 1.1)

This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other devices on this system.

I let Microsoft run "Fix-It" and it says Mobile Intel(R) 965 Chipset Family (Microsoft Corporation - WDDM 1.1 us not working properly. AND Hardware changes may not have been detected

Is there a way to fix this? I"m just trying to get one machine working. Thanks for your help

Answer:Solved: Swapped hard drive Error Code 12

Are you saying you put the hard drive from the Amd machine in the Intel and tried running that operating system? If so you can't install a drive with a previous os installation. The chipsets and other hardware are different. You need to do a fresh install if the above is the case.

I recently got a new hard drive. The first thing I did was create a new partition. After that, I copied the contents of my C drive to the new partition using HDCopy. Next, I changed the letter of my C drive(changed it to Z) and changed the letter of my new partition to C. Now it looks like everything works, but I do have one question.

Hi, I'm new to these forums and Win 10.

I've just purchased a used (clean OS install) desktop with Win10 pro installed. It has a primary SSD drive, and a storage 3GB magnetic hard drive. I attempted to unplug the existing 3GB drive and replace with a 1GB magnetic (storage, not primary) hard drive from my laptop to transfer many large and important files onto the desktop primary drive. This has worked without trouble in past years on many machines with older Windows OS etc. However, after startup I was aghast to discover that all of the files on the 1GB (laptop) drive now in my Win 10 machine have apparently been deleted, and appear to be replaced (at least in name) with two small folders of the same name that were on the original desktop 3GB. This seems confirmed when I replaced the 1GB drive back into my laptop. Also, I notice that the 1GB drive which is now back in my laptop has been renamed as a 3GB drive. This is a completely unexpected result, and many of the files are irreplaceable. Is it possible to recover these files? Hope this makes sense...

Hey guys, kinda new here, hopefully I'm posting this in the right forum section.
I'm not that super oriented with computers, I'll give it my best shot to explain what's going on here.
In short my PC just won't start. The light turns on, it boots up, and then I get a black screen with text referring to either "Start Up Repair (recommended)"
"Start windows normally"
If I choose start windows normally, it brings me to the black booting screen with the windows flag, then it proceeds to go back and restart the system, going back to the black screen. OR More likely it just stays stuck on the glowing windows flag.
This also occurs if I press F8 and go into safe mode. After listing all the components before going into safe mode, it simply restarts itself and goes right back to the black screen of the two choices.
If I select Start up repair, a grey loading bar appears below that on occasion freezes. If I manually reset the computer try it again, I get to a blue windows default background screen and the message

Answer:Windows 7 won't boot past possible broken Hard drive attempting to recover/clone/copy hard drive

It sounds to me as if your Operating System has been damaged beyond repair, and that you only option would be to re-install your system using the 'Return to Factory Settings' facility provided. Unfortunately, this would mean you would lose all you data, and, from what I can tell from your posting, you have not taken a back-up so you cannot repair your PC at present.
You first need to remove your heard drive and connect it to a working PC either as slave or in a caddy, and use this to copy all your data onto a new external device.
Once connected to another device, you could partition your Hard drive and copy your data into a second partition.
Once you have your data copied, return the HHD to your own PC and re-install your system from scratch.

I hope I can get a guru on this, because I think my situation is kinda unique, since google or search hasn't helped....

I built new machine using all my old drives laying around, 6 in total so far.

when I installed winXP pro, I had an issue deleting a particular partition on a particular drive, it wouldn't do it, saying it was a system partition. I didn't think much of it, and just continued on installing, which was a different drive. I figured I would take care of it within windows itself.

well, the result is odd; I have windows installed on D:/ and as it turns out, the drive in which I could not repartition or format is now labeled C:/ in disk management, and I have zero options within disk manager to reformat or repartion that drive.

In manager, C:/ says it is a Dynamic Drive, and that it is a System Drive, which isn't true because there is zero data on that disk, and it's secondary partition is drive I:/ (the later information probably isn't important, just thought I would tell you how windows named the drive and partition.)

In manager, Drive D:/ is labled as a Basic Drive and it is the Boot disk.\

seem odd so far? yes...

as I continue, I tried unplugging drives to figure out which physical drive is this mysterious Dynamic System Drive, and if I unplug it, even though there is no data on it, windows will not boot.

I have an HP Pavilion p6240f desktop purchased in 2010 that came with a 750GB C: drive. I'd like to replace the drive with a new 3TB drive using a cloning program to copy the old drive contents to the new drive. I've read that to access and boot from drives larger than 2TB "your system must be UEFI-capable".

I've looked around on HP sites and other places to determine if my desktop is UEFI-capable but have been unsuccessful. Can anyone tell me if my desktop will work properly with a 3TB drive?


Answer:Problem Replacing 750GB Boot Drive with 3TB Drive on older Desktop?

You can plug in the drive alone, attempt in Disk Mgmt to initialize it MBR creating a partition smaller than 2tb. If it will allow this then you'll be able to clone or image over the old install to that partition.

You might even be able to create other partitions once you initialize it with a partition smaller than 2tb for Windows.

I've seen a similar problem in this forum, but I can't find the identical problem or a solution.

Simply stated, I made a copy of my w2k hard drive using ghost and when I try to boot to it, I get an error to the effect that the page file is missing or too small. Safe mode doesn't work either.

Read on for more details. I have also posted this to Western Digital and am awaiting an answer from them.

I want to install my new drive as my master because I believe I am having errors with my existing drive.

I have a master drive (C: ) and a slave (F: ). Most of the data on the slave got there by running the drive to drive copy (not the install new drive) selection from data lifeguard (Western Digital utility).

Because I learned in the past that I cannot successfully boot from the copy made by data lifeguard, I used Norton Ghost (version 10.0) to copy from my old master to the new drive. Ghost has an option that says it can be used to install a new drive.

I'm pretty sure I kept the jumpers and physical drive locations straight through all of this. Here is where I am at. I was careful.

If I try to boot from the new drive as master with no slave, the boot fails. It tells me the paging file is missing or too small. I do not have this problem booting from my old master with no slave. In both cases the slave is physically disconnected. If I attempt safe mode with the new drive, I have the same problem.

I have a Y500 model that originally came with a Samsung Spinpoint 5400RPM 1TB HDD + 16GB SSD cache mSATA drive. The original drive failed a few days ago, so I have decided to not only replace the new "spinning" drive with a 7200RPM model but I also bought a Samsung EVO 850 mSATA 128GB drive. At the moment, I have only inserted both drives into the laptop and they are both completely blank. I went into the BIOS and it shows 2 Hard Drives recognized both the 1TB "spinning" drive as well as the mSATA SSD. The mSATA was labeled Hard Disk 1 and the 1TB as #2. Unfortunately, I didn't create my recovery USB media until the original Spinpoint drive was at about 70% drive health according to Acronis Drive Monitor. I didn't receive any errors but I am skeptical on the stability of all of the recovery media that is contained on the USB flash drive. Anyway, what option should I take to make the mSATA SSD the primary boot drive with the OS and programs and the 1TB as the data only drive for everything else?

I have a Dell desktop Core i5 PC about 3-4 years old with 2 SATA drives and 2 DVD RW drives. I had the boot drive (a Samsung EVO850 250Gb SSD) partitioned into two drives, C 150Gb and D about 85Gb. The other HD is a Seagate 2TB which is partitioned into 4 drives, E, 700Gb, F, 600Gb, G, 500Gb, H, 100Gb (sizes approx.). This configuration has been working well for about 2 years, since the time I installed the original SSD.

Recently, the SSD failed and had to be replaced by Samsung. (Their SSDs have a lifetime warranty.) While waiting for the replacement SSD to arrive, I put in a mechanical 320Gb SATA HD, installed Windows 10 Pro (the same OS I had on the failed SSD). Install went fine, but on the first reboot to the desktop, I discovered that the system did NOT detect the 2nd HD, the 2Tb Seagate.

I removed the 2Tb and used a dock to connect it to by wife?s desktop, and her PC detected the drive.

However, after putting it back into my PC and restarting, the system DID detect the 2nd HD, and I was able to access the files on all the partitions. On every restart since, I had no problem accessing the drive and all files.

Fast forward about a week. Replacement SSD arrived. Rather than start all over again, I tried to clone the C and D drives from the 320Gb temporary drive, and had the new SSD connected to a USB port via a dock. The cloning operation needed to reboot to actually begin copying to the new SSD, but I was unsuccessful because the system did not detect the SSD in... Read more

Worked the first time, but since then, boot up leads to "error loading OS" message unless I disable the secondary IDE (the one the with the new data drive attached) in the BIOS Can't see anywhere in the BIOS to set the boot drive -- is there a boot disk or other workaround?  --- Oh, separate problem -- the CD burner / DVD reader drive has been having some trouble reading DVD data disks.  (No problem reading data CDs though.)   Sometimes the problem results in sticking a DVD in the drive and it doesn't even find the files.  (The DVDs still work fine in another computer.) --- Thanks!

I had an 80GB Seagate IDE hard drive in my Dell Dimension 2400 that was clearly dying. I have been using a boot CD to connect to the Internet for days now. I have replaced the old hard drive with an unused 250GB WD IDE drive and with difficulty gotten the computer to recognize it. I intended to boot to flash drive and use the boot CD to execute the transfer of an image of the old Seagate drive from its location on my external hard drive to the new internal hard drive. But the computer will only boot to flash drive when the new internal hard drive is removed. When the drive is in and I click Enter on "6. USB Flash Drive", I get the ""Strike the F1 key to continue, F2 to run the setup utility" message over and over.

When I take the hard drive out, I can boot into flash drive again. I have A05 BIOS, and it appears to me from the Dell website that is as far as I can go.

How can I start booting into flash drive with my new hard drive in place, just as I did with my old hard drive in place?

I had a regular install of Windows 7 on a WD 1 TB drive with the usual C:\ as the boot drive.

I just got a new SSD, so I set up a parallel or dual boot of Windows 7 on the SSD which is set up as the B: drive.

So when I boot into the Windows on the SSD (B:\) and run the WEI, it fails because it can't write a file to the drive.

Any suggestions? - I don't want to start changing the drive numbers as that will mess up my file associations. I tried editing the xml files under the Performance directory, but still can't get it to work.

Answer:WEI fails (cannot write file to hard drive) Boot drive set to B:\

Generally B: is not assigned to a hard drive, but can be used for a volume. I don't know if this is the reason you are having problems. I'd think modern BIOS might not have an issue with this, but older BIOS always assumed A: and B: were floppy drives. A Guy

I've got a customer with a Y580 who wants to upgrade to an SSD.  Only, in asessing the laptop for the upgrade requirements, I see it has a 64GB mSATA SSD.  I think it's configured as a caching device.  Is it possible to set it as the boot volume and just install Windows there?

Answer:Use mSATA drive on Y580 as primary system boot drive?

It is possible. You'd probably need to uninstall the cacheing software, but I'm not sure - check the BIOS to see if it comes up as a boot option first. Once you can get the computer to recognize it as a drive you can boot from, install Windows on it and move it to the top of the boot order.

I have Vista Home Premium with two 320 GB internal hard drives © & (E). I am trying to put Vista on drive E and upgrade to Windows 7 on drive C.
I had successfully cloned the drive C of Vista onto an external hard drive and copied it to drive E (the second internal hard drive). When I copied the cloned copy of Vista to drive E, the system changed the drive letter to L. Everything was working fine and I could boot into either C or L.
In a fit of neatness I guess, I decided that I would like to have the newly labeled drive L designated as drive E again and changed it to drive E in "Disk Management" while I was booted into drive C.
Now I am unable to boot into the second internal drive. I just get a blank screen. I can get "Task Manager" but nothing else, not even the "Start" icon.
I booted back into C and changed the drive back to L, but that didn't work either.
I tried to boot the second internal drive in Safe Mode, but just got a blank screen, without the start icon.
I tried restoring to a previous date, but that wouldn't work and it only restores C anyway.
When I'm booted in drive C, it shows the second internal drive L and shows all the files and programs that should be on drive L.
How do I get the drive restored so I can boot into it?
Thanks to anyone that can help.

Answer:can't boot to second internal hard drive after changing drive letter

I don't know if this helps, but is drive L still marked as an "active" partition in disk management?  When you right click the partition the option should be there to do so if it is not marked as such.

Answer:Boot up error 0xc00000e9 after formatting a usb drive (disk drive)

Hello and welcome betodc mate what is the machine make and model? Because usually to do a factory default you only need to power up and at the same time tapping the default key which is different for different brands, For example for Toshiba it is 0'

That takes it into a recovery partition - I personally have never used a disk or drive when defaulting.

I recently had a computer custom built at a repair store. A couple of weeks back my start menu stopped working because of a Windows 10 update. I decided to wipe everything and reinstall Windows. I have done this many times in the past on other computers with no problem. This time it was quite a headache. I have 2 hard drives. I first removed the data from both drives, then assumed Windows should be installed on the smaller drive. After installing there I realized I had no access to the larger drive anymore. So I started over and installed instead on the larger drive. After doing this I finally admitted that I had no idea what I was doing. I brought it back to the repair store and asked them to make it the way it was when I bought it. They did so with no questions asked, but I'm worried about it happening again. The main issue is I have no idea how the two drives are configured. If I need to reinstall Windows again, how can I set this up correctly?

These are the two drives I have:

Boot Drive: Samsung 850 EVO 120GB SSD
Storage Drive: Seagate Barracuda 1TB HDD

Thank you!

As far as the recovery partition, if you still have the option, I would make the recovery DVD set. I don't know if these are hard wired to expect to be on certain disk sectors. Maybe someone who has Acer can chime in. But according to Easus user manual, the disk clone will copy the entire drive as long as the new one is of equal or larger capacity.

I wish to format an external Hard Drive for Windows 10 and then install the Drive into my Laptop and load Windows 10 from the DVD I created from the ISO file.
My reason for doing this is to get a completely clean install, as every other time I have tried I end up with a poorly function Windows 10 PC and some of the old information such as Wall Paper, Network setting, Home Group etcetera are still set up in the New "clean" installation which I believe are causing the very slow Boot up along with other problems. Each time in the past I have agreed to "keep nothing" but that does not seem to work!

Answer:Format external Hard Drive as a boot drive

plug into another PC using a usb caddy
the drive will appear in disk management either right click and select format (do not do a quick format) or you could use command prompt (admin) and run diskpart to remove all partitions and make just one partition on the drive before formatting.
refit in the laptop
ensure DVD is set as first boot device
insert DVD and and press any key to boot from he windows iso (DVD must be bootable made using windows media creation tool for w 10).
follow the prompts to install windows (you cannot install windows onto the drive while it is in the us caddy on the other PC).

Although my Disk 0 (see attached Computer Management jpg) displays itself as the boot drive, it will not boot up alone. I must power up a second drive (labeled Disk 1) to view Disk 0. I understand the need to use the BIOS to point to the Boot Drive and Boot Priority, and have done this each time.

This is not a BSOD issue.
I have multiple W7 operating systems installed. One on Disk 0 and one on Disk 1. I am offered a choice when booting from Disk 1, to choose operating systems and I select the one located on Disk 0. (Verified by the jpg file.)
But with only the Disk 0 receiving power, I get a message that the drive will not boot unless I insert a bootable disk.
However, with both the Disk 0 and the Disk 1 drive receiving power, I manually change the BIOS to point to Disk 1 to allow both drives to be viewed successfully.
I would just like to use Disk 0, but since it will not boot by itself, (even though it shows it is the bootable drive), I must be doing something wrong. How can I use only Disk 0?

Answer:Boot Drive Only Successfully Boots with Second Hard Drive

This sounds like a problem for gregrocker

The 100MB partition on Disk 1 is marked as System so that's where the boot files are located and why you need to to boot.

I believe you can fix this by removing Disk 1, booting your Win 7 DVD and running Startup Repair up to 3 times: Startup Repair - Run 3 Separate Times

My Corsair 240 GB SSD just crashed, as Boot C: on my games machine. I was lucky to be able to save most data I wanted to keep via my network before full failure. But Now I have a Crucial 960 GB SSD to replace it but am confused how to install it and reformat it as my boot C: drive .. when I cannot find (or maybe forgot to create) a boot disk ... I do have my original W7 install CD but that's all i got. Is there a simple way to create a boot dsk that will allow me to format my new SSD, to reinstall W7 ?? Will the BIOS allow me to do that ????

BTW, I performed a CHKDSK (fixed bad sectors) on my old SSD, which continually crashed to BSOD half way through, which i needed to reboot meaning CHKDSK would start again, never ending cycle (Hit any key to stop CHKDSK doesn't work because the keyboard is turned off when that happens, for some strange reason??). I hope CHKDSK is part of a AUTOEXEC.BAT and not the BIOS because I would hate to have this start over with my new SSD installed.

BTW, I pretty annoyed my Corsair only lasted 2 1/2 years, I realise it should be still under warranty but I want to upgrade to something bigger.

The manual for setting up SATA RAID0 leads me through to the installation of the OS which I do not need.

Once I set up the BIOS and Raid0, the machine does not boot as it cannot see the IDE boot drive. It sees it as a SCSI. Do you have a method of setting up the raid such that it does not become the boot drive and simply functions as a striped DATA storage ?

My SONY computer, XP Home installed, recently needed a new HD due to the main 15 gig partition on the original 120gig HD was getting full and causing problems. I installed a 200 gig HD and restored the default factory load to the new drive, then installed all of my software back again.

The problem is: When the restoration was finished, instead of using all 200 gigs of the new drive as a single partition, the Sony restoration package made the boot partition15 gigs again. I cannot find a way around Sony's software to make this partition larger. I don't think it's possible to increase a partition without formatting the disc, is it? Right now, with a barebones load of software that I use, I have 500 MB of disc space on the C_Drive. That's just not going to hack it.

I do have a new copy of XP Home and could start from scratch, however I'm a little wary that drivers and such may be missing... Sony is so proprietary about things, I'm afraid I may lose key features of the computer. Any suggestions?

How about this... Clone the contents of the 15 gig C_Drive partition onto a new HD and ideally, into a 50 gig partition to become the c_Drive on that HD.

Is that possible? Or is there another way?

Answer:A way to dump a boot drive to a larger drive but with a twist...

yes, there are several ways. CLONE the drive with proportioning.

Answer:Hard drive tray used to swap W7 boot drive?

Hello randyrls, welcome to Seven Forums!

This would be a whole lot easier, no swapping HDDs around, you don't even have to power-down, just reboot.


The easiest way to do away with boot issues between separate Operating Systems (OS) is to use the BIOS one time boot menu to select which OS to boot at system startup, each motherboard has an individual hot-key to tap during system start-up to access this menu.

If you have 2 separate Hard Disk Drives (HDD) and have one OS installed to one HDD and you want to install another OS to the second HDD, disconnect the HDD with the first OS installed on it and leave only the HDD you want to install the second OS to connected.

Install the second OS to the connected HDD and when complete and the system is booting good, power down and reconnect the first HDD with the first OS on it.

This way the OSs will boot independently of each other and there will be no boot conflicts between the 2 separate OSs to have to sort later.

Then set the BIOS to boot the HDD / OS you want as default and if you want to start the other (new) OS you use the BIOS one-time boot menu to select that HDD / OS to start when the PC is started.Asus - F8

I have an SSD that I want to install my operating system on, and make it the boot drive. The reason being that some software will default to install on the C drive automatically, without prompting for another option, so I want to use just a regular hard drive for data and some programs, and I want this to be the C drive. Boot from the D drive, which will be the SSD.

Does this make sense? How do I go about this? Thanks!

Answer:I want to make my D drive the boot/operating system drive

If you install windows 7 to the ssd in the normal way, using booted media e.g. the dvd , it will assign itself letter C.

It is possible to assign a different letter during boot media install - but it's complicated.
If you already have windows 7 installed on the HD ( I assume it has already itself C ) - running setup from there and pointing it at the SSD will cause the installer to use the next available letter.

That will be much easier for you.

Is it possible to discover the previous drive letter assignments on an old boot drive?

I have a Windows 7 boot drive that previously was part of a system with 8 hard drives. I cloned the boot drive from this system and moved to a newer system, on which I've since done an "upgrade in place" to Windows 10 Pro. I have some software that expects the drive letters be the same as the old system (in order to find certain resources.) Ideally I would like to simply change the drive letters in the new system to match the drive letters in the old system, unfortunately, I don't remember exactly what those are. So ... instead of testing a bunch of different letter assignments, I was hoping this information might still be available on the original boot drive. Any help is appreciated.

...and be recognised to it's true capacity?

Windows XP (without SP2) only recognises drives up to around 127 gig.

If the drive is formatted thru Computer Management console (with SP2) and is then used to start the install of XP, the installation process doesn't recognise the large volume as being valid (it considers it corrupt/unrecognisable) and requires it to be formatted again (which will then reduce it to around 127gb).

I haven't actually tried partitioning the drive first but don't really want to and doubt it would matter in any case.

I want to use the hard drive, to it's full capacity of 300gb (279gb in reality), as the master boot drive.

Is this possible?

Answer:Can a hard drive larger than 127gb be used as the boot drive...

Hello and Welcome to TSF

No, it will not get the full 300gb, thats just the way it is. There is always so many gb that will not show.

Some Manufacturers say "Gigabyte" when they mean 1,000,000,000 (10^9) bytes. When your operating system says "Gigabytes" it means 1,073,741,824 (2^30) bytes. This means in your OS the drive appears smaller.

How can I get my computer to boot off of my original drive? And why would once booting from another drive screw up my original drive??

Also, if it's of any use / help - my new motherboard is a UEFI-enabled one, an ASUS Z77 Sabertooth...


For some background - I purchased a new motherboard recently, and decided to just install a fresh copy of windows 7 when I did so. I purchased and installed to a new hard drive... everything was working fine - it was booting, starting up, etc. Then, I decided I wanted to grab some files off of my old drive - so I shut the computer down, hooked it up using an enclosure + an esata cable, then restarted... on startup, it recognized my old (now external) drive, and booted off of that. I then restarted my computer, checked the boot options, and set it so it SHOULD boot off my new (internal)... but it still booted off my old (external) drive. Finally, I disconnected my old (external) drive completely... and that brings us to where I began: with my new (internal) drive completely unable to boot.

Answer:Can't Boot from orig. drive after attaching/booting from other drive

Ok, I guess I solved my own problem... going to post in case anybody else has a similar issue...

I got it to boot by setting the boot priority of the "Windows Boot Manager" BEFORE the priority of my DVD-drive. I guess I'll have to manually go into my BIOS to change the settings every time I want to boot of a CD/DVD. Annoying... but it works, I guess...

How to change default boot drive and reformat the old one.

I installed a new 2TB drive and installed window 7. But for some reason win7 needs my old drive to boot. I have tried to unplug the old drive and boot with the win7dvd, but I get disk failure message please reboot over and over.

What are the steps to make the new drive the sole place for win7 to boot and then how can I reformat the old drive for storage?

Thanks for any help provided!

Hi Guys,

I need help with this situation:

I've cloned a 1GB CF with XP embedded and image it onto a 2GB CF, but the new 2GB CF is getting stuck while booting.

The boot process would get stuck somewhere within in "PCI device listing... " .

Obviously, it seems like the system doesn't like the boot disk size change, but I don't know how to fix this.

Can someone help me resolve this?

I have a Toshiba Satellite S75-B7314 A660 services. My internal CD/DVD drive has failed. I tried to diagnose the drive with changing REGISTRY settings, updating drivers with no prevail. The drive cannot read any data, when I put in media, I get a response that says please insert a disc into the drive. This all started I believe when I downloaded/installed Window updates, not sure though.

So......I purchased an external CD/DVD drive. I'm formatting the laptop and cannot boot from the external drive after setting the BIOS to first boot from USB, boot up the laptop and goes right into Windows, ignores boot up. I tried different USB ports with no luck, changed the boot mode to UEFI (it's on CSM now) and does not read a bootable device, giving me an error message, No bootable device, please re-start system.

I guess I can buy a new internal CD/DVD drive and return the external drive, but want to know if the external drive is actually failing. I still would like to use the external USB drive but don't understand why I cannot boot from it.

I know this question gets asked alot, but I have windows 10 installed on my 120gb ssd, I also have a 1tb hdd that has nothing no it and is completely useless because all of the program files etc is installed on the ssd, the ssd is nearly full too, is there actually a safe way of doing this? I'm quite new to this too.

Answer:Moving programs from boot drive to storage drive

Keep you OS and Programs on the SSD, but store all you files on the HD.
To move them you can "Drag and Drop" or "Copy and Paste". Do not delete them until you are sure that the move has been successful. When saving new files, select "Save As" and specify the HD Drive letter.

I bought a new Dell M3800 laptop and it worked fine for three month.
One morning it refused booting. The Dell Windows Recovery CD will not load either Just goes to black screen.
I tried everything I could think of and everything I found on google with no luck.
Yesterday I removed the HD and connected it as an external drive changed the Boot options and it worked.
But it still will not boot when connected internally. The Dell diagnostic tool does not find any problems.

Dell M3800.
SSD 250GB drive.

Please help. What could be causing this?
