Preferred Solution: Laptop booting up with UEFI please help

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 http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Laptop booting up with UEFI please help

Are you talking about UEFI (more commonly, and mistakenly referred to as bios) setup before the computer boots into Windows, or are you talking about a failure to boot from the hard drive? If you are talking about the UEFI settings before the computer boots, we need to know the exact model Asus Laptop.

Hi

On this new laptop which appears to have UEFI and Legacy BIOS settings, setting UEFI settings to boot from DVD or USB first in order to run a bootable format disc to preformat before a clean install has thrown an error message that ..."boot from [xx device] failed." This was with the GParted.iso installed on disc or USB.

I did not touch the Legacy BIOS boot order just the UEFI boot order as information given suggested that the UEFI takes precedence.

In the end I formatted using the windows installation iso and format tool, booting from USB which worked. But this has meant that I get the windows recovery partitions that I was trying to avoid. Having got here, I think I will leave it like that as it probably makes sense and I suppose windows will probably run better with them? This has got rid of the additional HP partitions and crapware which is also what I was trying to achieve.

Just wanting to know for future reference, if I do want to boot from DVD or USB on this laptop OTHER THAN with windows installation .iso, how would I do it?

Thanks again in advance.

Answer:UEFI laptop, booting from DVD or USB fails

But this has meant that I get the windows recovery partitions that I was trying to avoid.



Hi, assuming you mean the 450Mb Recovery partition, you should keep that. That is for- guess what- recovery. Without that you have no Advanced troubleshooting options or automatic recovery. It's small- so you gain nothing worthwhile by not having it.

You could have removed all the additional stuff that came with your laptop without doing a clean install, and partition managers allow deleting the recovery partition.

Does your DVD boot up successfully on a different PC? Is there some chance it was not burnt successfully?

You may wish to check with your manufacturer about booting from a DVD. For example, on mine, I have to hit F7 to display the appropriate boot menu. Yes, F7. That was unexpected. And the option to select the DVD drive is described in a totally obscure way.

(Laptop = Toshiba Tecra A11 if anyone's familiar with it)

So basically back in the days a simple as F8 boots you to safe mode or F12 could bring up boot menu where you could boot from a flash drive or an optical disc , use a tool like hirens boot cd to undo the mess or just do a windows upgrade and you are good .

Now what's the new trend as UEFI bioses just lock you out from both bios and boot menus unless you legitimately pick those from inside OS menus , a friend had his windows 10 falling into some boot loop and all i could think of was to unscrew the hard drive and work on it externally , is that the trend really or am i missing something ?

It can be tricky getting to Bios if UEFI, particularly if fast boot is enabled.

There are several tricks to force getting to bios

1) See if bios has jumper settings you can change to make it boot to bios

2) Remove CMOS battery which often forces a jump to bios to reset date/time

3) Remove hard drive, and boot with a windows 10 installation flash drive or dvd inserted. As it will not detect hdd, it will boot from usb drive or dvd next, and using repair options, you can get to the bios via the repair menus. This is probably easiest to try first.

Once you get to bios, you can set boot order to boot from usb drive or dvd first. Then replace hdd and boot from flash drive or dvd. I always set the boot order to boot from flash drive first on any new pc, so I do not get caught.

Question: UEFI booting

I created two UEFI bootable USB drives:
USB stick 1.) using windows 10 "create recovery drive" - on a 32GB usb 3.0 drive
USB stick 2.) using EASE US backup/restore software - on a 4GB usb 2.0 drive

Both sticks appear to be UEFI. When I put them in my windows 10 desktop machine, they both show up in the boot menu as "UEFI:" followed by the usb stick brand name. Stick 2 also shows up a 2nd time in the boot menu, with the brand name but without the "UEFI" in front. When I select Stick 1 from the boot menu, the desktop machine boots, asks for the keyboard type and continues to the recovery program. However the desktop will not boot to Stick 2 using either of its boot menu choices.

Then I tried them in my Lenovo Yoga 2pro laptop (now with windows 10). The only way to get the boot menu on this device is to power down and hit the small button on the side. Stick 2 appears in the boot menu, and when I select it the EASE US backup software starts. Stick 1 is a different story however. I can boot to it by selecting "Advanced startup" under Settings, Recovery and then it boots and behaves like it did on my desktop machine. However it does not show up at all in the boot menu, and thus there would be no way to boot to it if windows was broken. (Kind of defeats the purpose of the USB stick!). I also tried this on a second Yoga 2 pro that I have and the results were the same. (I've already disabled the "secure boot" option in the BIOS.)

Answer:UEFI booting

Is your stick 1 formatted with NTFS ? If so, recreate it but format it with FAT32 because some earlier version of UEFI firmware won't boot if it is formatted with NTFS.

Laptop is a gateway nv510p04u

Running Ubuntu 14.02.

Recently bought the laptop and have issues getting it to boot usb or cd.

I was able to disable secure boot but when I try to switch the bios the only option I can select is UEFI (I was told I need to boot into legacy).

I am trying to uninstall Ubuntu and reinstall Windows 8, but I can't do that without booting from cd/usb.

Hi all,

Just did an upgrade that included new MSI PC Mate MB and i7 4790K CPU - all went fine. Did a fresh install of Windows 7 Pro 64.

The Bios of the MSI gave me fits from the get go as far as booting. I initially installed OS in UEFI/Legacy mode. But did some switching to UEFI in an effort to get the boot correct (kept wanting to boot to other sata drives). It seems that at some point it stuck in UEFI mode - see below bcdedit /enum report. Now it will not boot in UEFI/Legacy mode at all (Please insert bootable media ...) so I'm running it in UEFI mode but at boot I have to use the Boot Manager and even choosing the correct disk I always get UEFI shell 1st time - second attempt gets me into Windows. Large PITA of my own making.

My question is how can I get the MBR back to standard legacy mode? Do I have to reinstall? Or maybe I can run a repair? I would hate to have to reinstall - I have a backup image - would that work or is the part that needs "fixing" on the image?

Thanks for any suggestions! I hope I was clear, if not please ask me. I'm not a rookie but not a full blown tech either.

Thanks!

Hi, I just purchased the HP x360 Spectre, which came with Win 10 Home and UEFI/SecureBoot turned on. The boot disk is GPT. Also, there are 4 partitions on the drive out of the box, as listed in the : EFI SystemRecovery PartitionRecovery ( D: )Windows ( C: ) This is my first Windows above 7, and the first that is not Legacy BIOS and MBR boot disk, so I'm a little lost with all this. I need to backup the drive before making changes to the new laptop using my Macrium Reflect Win7-based PE USB pen drive, but when I disable SecureBoot and enable Legacy Boot and move USB key to the top of the boot list, it boots Reflect under PE OK, but no drives are shown in Reflect to back up. I'm not sure at this point if this is because Version 5 of Reflect doesn't support UEFI (although I'm not sure that's a factor as I've booted), or some other factor resulting from UEFI and GPT. I know Reflect V5 can backup GPT drives, as I do it now, but have only imaged MBR drives. There are newer version of Win PE; Ver 4 based upon Win 8, and Ver 5 based upon Win 8.1, which might solve my problems. I'm trying that next. If anyone has any insight, it would be much appreciated. Also, are UEFI and BIOS connected in some way to MBR and GPT, so that one requires the other, or can you mix and match. For example, could I have machine using UEFI and an MBR boot drive, or vice versa? I'm just not sure what, at this point, is making my drives not appear in Reflect. Also, is there a way to conver...

Hello guys.

I plan to triple boot Windows 8.1 Pro, Mac OS X Mavericks and Ubuntu 14.04 TLS on my machine.

I just had a few question regarding the same and some questions about UEFI & GPT.

Now, I'm going to format my entire drive and install Windows 8.1 in UEFI mode. So the hard disk will be automatically formatted to GPT instead of MBR right?

Also, my graphic card (MSI R9 270X HAWK) doesn't yet support UEFI/GOP so even if I do install Windows 8.1 in UEFI mode, I can choose not to use the UEFI option?

My hard disk being GPT formatted during the Windows 8.1 install in UEFI, will I have to apply any patches to install OS X (which will be on a separate partition)?

Should I install OS X first as it uses GPT and then install Windows 8.1 in UEFI mode on a separate partition?

Lastly, after installing OS X and Windows 8.1, how do I install Ubuntu in UEFI mode (if it supports UEFI) and configure the boot menu so that I can choose which OS to boot into?

Thanks in advance.

Regards,
Yash Shah

Answer:Problem with booting in uefi mode

hi Mortaza,
 
Welcoem to the Forums.
 
Just to verify, did you created a bootable UEFI Windows 8.1 installer via a USB flashdrive? If you did, this is most likely blocked by the settings in the BIOS as the system is bypassing it and is trying to boot via LAN.
 
Try to:
1. Boot in the BIOS and set the following:
 
Security Tab:
Secure Boot = Disabled (if applicable)
 
Exit Tab:
OS Optimized Defaults = Disabled / Other OS (if applicable)
 
2. When done, press F10 to save and exit and repeatedly tap F12 and see if you can boot from the UEFI Windows 8.1 USB Installer.
 
Let me know how it goes.
 
 
Regards

It might be worth it to make a sticky referencing the Windows 7 tutorial for creating USB flash installation media, specifically the part 11 about moving the EFI files around. I have been bashing my head trying to figure out why my laptop refuses to acknowledge ANY USB Media (never tried CDs) and the conclusion I came to was that my laptop had booting from USB disabled, NOT that the ISO still doesn't have working boot files when flashed with Rufus.

It would've been nice to know before caving and upgrading (and subsequently downgrading) my Windows 8.1 install.

I am sorry that I'm ranting about this, but I honestly did try searching the problems and such, and not finding anything I assumed that it was a problem with my specific hardware.

I'm sure it is obvious where to find it, but it would be nice if in the installation and setup forum there is a sticky with links to relevant tutorials (such as setting up dual-boot, making a USB flash drive, installing the TP in a virtual machine)

Welcome to Sevenforums,

An update might have changed/reset the way in Bios the primary disk boot. Check in your Bios settings for disk options if its set to AHCI, IDE, or RAID mode.

Choose AHCI if you're not doing any RAID0/1/5/10

Answer:Partition resize, Windows 8.1 not booting, UEFI

Just to update, I've gone through the BIOS, tried disabling secure boot, swapping between UEFI First and Legacy First, but cannot get the windows dvd (I've tried the windows 8.1 dvd (don't have the repair disc)) to see the partitions or even refresh or reset, it gives the error "the drive where windows is installed is locked" or "unable to reset your pc. a required drive partition is missing", but the minitool wizard sees the partitions just fine. I've tried several discs such as hiren's cd just to try to get to a GUI (mini windows) but always get a bluescreen (trying to load the GUI). I tried GParted, also no luck.

I tried the System recovery from the Novo Button Menu, but all I get is "Default boot device missing or boot failed" it then demands installation media which I already know won't help with recovery.
Would it be right to assume (since at least some tools can see the partitions)
that it is simply a problem with how the partition table is being identified? If that's the case, is there any software tool that can correct it?
I'd rather fix the problem than reload the whole thing (but it looks like I'll end up doing just that), any ideas?

Answer:UEFI Booting/ Enabling BIOS Features

hi lks1981,

Welcome to the Lenovo Community.

The Lenovo G475 only have the old Basic Input/Output System (BIOS) and doesn't have a UEFI as an additional option. Until such time Lenovo allows flashing of the BIOS to convert it to UEFI, you can't yet enable this option.

If you want to transform the BIOS to UEFI (to allow booting from HDD's larger than 2TB and up to 128 partitions or mix MBR with GPT type partitions) , you can try to use Developer's UEFI Environment (DUET), you can find more info here - http://tinyurl.com/d9owxqr

Hi

I have a system recently converted to UEFI using MBR2GPT. Today I created a bootable DVD using Kyhi's Recovery Tools ISO and want to run it up to find out exactly what I've got and how it works. Snag is I can't boot up from CD or DVD - my system just hangs.

I've done some searching on the internet and find that I have to disable Secure Boot in the UEFI firmware. I can't, I haven't got that option - although I have been told that Secure Boot will only appear if I have UEFI Only selected. It doesn't, I've checked. What I do have, however, is a setting called Storage Boot Option Control with the options Disabled, UEFI Only, Legacy Only, Legacy First and UEFI First - in that order. Does that mean anything to anyone? It's a Gigabyte Z97P-D3 mobo. When I converted to UEFI I made no changes (under advice) to my mobo firmware which is set to UEFI and Legacy - the other options are UEFI Only and Legacy Only.

When it comes to the boot sequence, first in the list is Windows Boot Manager followed by the disk model - the CD/DVD reader is second. Swapping them around just results in a flashing cursor on the screen.

My question therefore is: just how do I get my PC to boot from CD or DVD? I have a strong feeling that NavyLCDR would say I should use BCDboot with the ALL switch to copy both the UEFI and BIOS files to the System Reserved partition since currently I only have the files for UEFI in there as far as I am aware.

When it comes to the boot sequence, first in the list is Windows Boot Manager followed by the disk model - the CD/DVD reader is second. Swapping them around just results in a flashing cursor on the screen.

My question therefore is: just how do I get my PC to boot from CD or DVD? I have a strong feeling that NavyLCDR would say I should use BCDboot with the ALL switch to copy both the UEFI and BIOS files to the System Reserved partition since currently I only have the files for UEFI in there as far as I am aware.

Hi,

I'm trying to make a Windows To Go image for my PC repair business using Rufus and a Windows 10 Pro ISO from MS Techbench. It boots perfectly fine on most computers except one. The computer I am trying to boot off is running Windows 8.1 with a UEFI bios. It's got a weird "EFI File Navigator" which is a pain in my rear end. When I try booting from it, it gives me an error. A picture of which is attached.


Any ideas?

Thanks.

Hi all,

Ok, I have a new lenovo ideapad 305 (system is UEFI boot), I used minitool partition wizard (on a bootable USB) to resize the c: & d: drives (to increase space on the D) but didn't touch anything else, rebooted into windows & it seemed nothing had changed, so I booted up again on the minitool wizard USB and the partitions were exactly what I had changed them to. Thinking this was really weird, I tried rebooting to windows & have not been able to get into windows since.

I've gone through the BIOS, tried disabling secure boot, swapping between UEFI First and Legacy First, but cannot get the windows dvd (I've tried the windows 8.1 dvd (don't have the repair disc)) to see the partitions or even refresh or reset, it gives the error "the drive where windows is installed is locked" or "unable to reset your pc. a required drive partition is missing", but the minitool wizard sees the partitions just fine. I've tried several discs such as hiren's cd just to try to get to a GUI (mini windows) but always get a bluescreen (trying to load the GUI). I tried GParted, also no luck.

I tried the System recovery from the Novo Button Menu, but all I get is "Default boot device missing or boot failed" it then demands installation media which I already know won't help with recovery.

Would it be right to assume (since at least some tools can see the partitions) that it is simply a problem with how the partition table is being identified? If that's the case, is there any softw... Read more

Answer:Partition resized, Windows 8.1 not booting, UEFI

I always recommend a person do a complete disk image using Macrium or Aoemi before moving partitions but that being said see this page. If you can get to a command prompt using the Windows install disk use the diskpart commands shown. If it does not work then I think you are looking at a reinstall.

Hi,I am currently trying to install Ubuntu alongside my windows installation but have had with no success. The issue is that I am trying to make a UEFI Ubuntu installation but I can't get the USB to boot at all. I have made the bootable USB using Rufus 2.15 with the following settings:Partition scheme: UEFI GPTFilesystem: Fat32ISO image: 64 bit version of Ubuntu 16.04 (written as ISO image, not DD)Regarding my BIOS settings I have turned off secure boot, USB ports are always turned on, USB boot is enabled, CSM/Legacy is off. Furthermore I have turned off fastboot in Windows.Trying to boot via USB-FDD, USB-CD or USB-HDD does not work, it just proceeds and initializes the Windows operating system. Therefore I would like to hear if any of you have had any success dual booting a UEFI Ubuntu installation alongside your Windows installation.

Good day,

I have an Asus Z68 mainboard with UEFI-BIOS. Windows 7 Professional 64bit is installed in UEFI mode on a GPT partitioned drive (SSD). It worked flawlessly.

Now I added my second, old harddrive, that is still MBR formatted.
Windows won't start anymore, instead I am seeing "Windows is loading files", then a blinking cursor, and that's all.

I have two options in BIOS regarding boot priority:
1) I can boot from the SSD as primary priority
2) I can select an option called "Windows Boot loader", I think this refers to the UEFI boot code that Windows wrote to the UEFI.

If I select the first option, I get the "Windows is loading files screen" and then the "Windows has detected a startup error, do you want to repair the system startup" screen. If I select "Start Windows normally", I get a blinking cursor and then nothing. If I select "Repair startup", I see "Windows is loading files", and then again the "Startup repair screen". It is an endless loop.

If I select the second option, I get "Windows is loading files", then a blinking cursor, and nothing more.

Is there any way to get my Windows to boot again without disconnecting or re-partitioning the old harddrive?

Note that the old harddrive is NOT for booting, as it is just a datastore.

"The UEFI secure boot protocol is part of recent UEFI specification releases. It permits one or more signing keys to be installed into a system firmware. Once enabled, secure boot prevents executables or drivers from being loaded unless they're signed by one of these keys. Another set of keys (Pkek) permits communication between an OS and the firmware. An OS with a Pkek matching that installed in the firmware may add additional keys to the whitelist. Alternatively, it may add keys to a blacklist. Binaries signed with a blacklisted key will not load"

New Windows 7 install on a computer with only one hard drive. However, I now have another HDD with data on it that I need to plug into my SATA port on my motherboard. Once I plug this other hard drive into the motherboard I am no longer able to boot into windows. When it boots it now takes me to a black screen saying that it can not find the boot device. Once I unplug the new HDD it boots just fine. I'm assuming this has to do with my Windows 7 HDD being given a different ID from Disk 0 to Disk 1. an easy fix would be to change the order of where my Hard Drives are plugged into the SATA ports on the motherboard. The issue is that I can not do this because the Windows 7 Disk is a SATA III 6Gb/s so i need/want it to be installed on the SATA III 6Gb/s Ports and the 2nd Disk is a SATA III 3 Gb/s drive so I can't install it on the 6 Gb/s ports on the motherboard. On my Motherboard it seems to order the SATA III 3Gb/s drives first on the Drive order and the SATA III 6Gb/s at the end of the disk ordering. So, right now what I believe I need to do is Change my EFI/bootloader to point to the new Drive 1 location instead of the old Drive 0 location. Normally this isn't hard with MBR because you would just go to Boot.ini and change it there with no problem. However, I am unsure how to do that with EFI boot stuff and I have not found the specific solution to do this through searching the internet yet.

OK, here's the deal... I've cloned the HDD onto an SSD, but I can't get it to boot.-- keep getting a notice to install the OS.  I know the clone is (should be) ok, because this is the SEVENTH SSD I've cloned over the past three weeks.  The only difference with this one is that it has the UEFI interface (with Windows 7 Pro 64-bit), and for some reason it won't recognize the OS on the SSD. The UEFI is set for: "Legacy Boot with Secure Boot disabled" (when booting either drive).The original drive is MBR.  I tried cloning the drive as MBR and GPT, but neither will boot.I tried cloning a different SSD to make sure it wasn't the SSD.I tried disabling the "UEFI Boot order"  (by unchecking it), but that didn't do anything. What I did notice was... When the original HDD is installed the UEFI BOOT MENU shows the drive in the list TWICE, once as UEFI (#2), and once as Legacy (#4) (with DVDRW as UEFI #1, and Legacy #3, then Boot from file as #5). HOWEVER, when the SSD is installed, the only option it gives me is UEFI.  If I DISABLE (uncheck the option) for the "UEFI Boot order", all it will show is the Legacy CDRW in the Boot Menu. I remembered having a similar problem with about a year ago on my own Windows 10 laptop having the same issue when installing a cloned SSD and then I was able to use the Windows Repair to fix it.  So I created a Windows 7 repair disk (CD), but it won't boot from the disk (it just comes to a blank screen--I've f...

So for the last 4 years I have played with linux installs on and off. But something I ALWAYS encounter, is when I eventually get tired of linux (from not being able to play my games), during the removal process I always screw up my bootloader then struggle to fix it. Is there something I can do prior to this that will help?

I'm only interested in UEFI mode anymore since if I use windows it is w10.

If I create a system image of that drive with windows, could I just do windows recovery and get back that drive erasing whatever was on it prior? Would this also set the windows bootloader as the primary?

For example , I want to play with VFIO. First, I want to preserve my virgin windows 10 install on my ssd via a system image. Then I want to wipe it and install ubuntu and then create a VM within Ubuntu running w10. If this all goes south could I wipe the ssd and use the system image to revert back to where I started?

Answer:Safely dual booting linux without corrupting Win. bootloader? (UEFI)

We recommend Macrium Reflect Free and creating a Macrium Reflect rescue drive:
Macrium Reflect Free

It will let you make a backup image of your SSD, and you can restore the entire SSD from the image, or just a damaged EFI System partition. Also when you boot from the Macrium Rescue drive, under the restore menu will be a utility to Fix Windows startup problems which is very good at repairing the EFI System partition and BCD.

This week, I encountered the following strange problem for which I haven't found a final solution so far, though I have found some bandaids. But having a complete solution -or at least a reason why this problem occurs- would be great:
I have a working installation of Windows 7 Professional x64 in UEFI mode. The main disk, SSD #1, contains the following partitions (using GPT): ESP, MSR, system, data. An additional disk, HD #2, with a single data partition (using MBR) is also attached to the system. With this setup, everything works fine.
Now, after adding another disk, HD #3, to the system -my old system disk (bootable, using MBR, one active primary partition and an extend partition with three logical disks)- Windows will no longer boots completely: The boot process begins, the Windows logo is shown. Then, a message is shown in text mode "Windows is loading files" with a loading bar. After a while the boot process stops and I am dropped into the EFI shell. After removing the offending HD #3, Windows boots normally again.

I tried removing HD #2 and only attaching HD #3 together with SSD #1, but this yielded the same problem. Using SSD #1 by itself works fine though. Booting from a Linux live-cd works without problems. All disks and partitions are found and can be mounted. There, I erased the disk signature from the offending HD #3 and now Windows was able to boot and also found all disks and partitions correctly. But after a reboot the same problem reappeared.

Hello there, occassional lurker, first time poster, hopefully someone here will be able to help

I've been setting my laptop to dual boot xp pro, and Ubuntu on a seperate partition. All was going well, until xp decided to die altogther. I don't have that error to hand, but it's gone a little further now.

Was going to install xp pro on a 3rd partition, and it started up fine. Now I can boot fine to Ubuntu, and the 2nd version of xp. However, the original xp is still having issues.

Now, when booting up, gets BSOD - bad_pool_caller. Code at the end is: 0x000000c2 (0x00000007,0x00000CD4,0x00000060,0x86F7E1FC)

Everything I've read suggests this is talking about a hardware or software conflict. However, I've not installed any new hardware. I suspect there is a software conflict between the two versions of xp, but I can't see how that can happen.

I can boot into the 1st copy of xp in safe mode, however, explorer.exe fails to start up. Tried running it in task manager to no avail.

I forgot to add - I am using GNU GBRUB to boot between the 3 operating systems.

EDIT 2: Tried it again to boot 1st xp in safe mode - new error for windows product activation - a problem is preventing windows from accurately checking the licence for this computer error code 0x800004005

Hi HP experts, I have been reading about UEFI and Gpt partition versus Mbr partition, and from what i understand about these subjects - the Gpt partition is to prefer if the laptop supports UEFI, because the laptop boots faster, but is that the only thing thats better about it ?I found the driver page for my Envy, and found out that under help program/tools, there were a program named HP UEFI-support (Unified Extensible Firmware Interface) . Now i am not quite sure if this means that my Envy supports everything about UEFI, because in my BIOS i dont seem to be able to find anything named UEFI ? But if i press F2 during bootup, i do get a menu wiith for example the opportunity to reverse to an older version of BIOS, and 4 or 5 other options to see what my laptop consists of.I also ran the CMD tool, and ran the diskpart and list disk commands, and the partition is not listed as Gpt, but Mbr, because there aint no * under Gpt column, and i think the only way i could make a clean install for several months ago, was to set the Rufus usb boot tool to Mbr, and then clean install Windows. If and only if you mean that i can gain anything by going the Gpt and UEFI way, by setting Rufus up to make the usb bootable this way, shouldnt i then just reformat to Gpt with CMD with these commands in the order : Diskpart-list disk-select disk-clean , and then shut down the Envy and run the usb drive ?  Further more i suppose the recovery file i made and saved with Ma...

Windows Update Failure

I found I can use msinfo32 from the cmd shell to see my BIOS Mode which indicates I'm in UEFI
So I'm not entirely sure what the problem is. I did some funky things when I first built and installed Windows on this computer about a year ago. I have a 3TB Hard Drive and a 500GB SSD. And I found out I wasn't able to use all 3TB without using a GPT. Found some guide online followed the steps and fixed that issue.

I think there was an issue after that where the 3TB hard drive had the Boot part on it, and I followed some other guide to get my SSD to be the boot drive. But I think what I did then has put something in a weird state thats causing the update issue above.

Heres the Partitions
And heres using diskpart

Can anyone help me work out how to roll back or dual boot with UEFI. I just got a new laptop which came with Win 8. Let's not debate the reasons but I am determined to go back to Win 7. I put my old hard drive with Win 7 from my old laptop into the second drive slot of the new laptop. I can read the drive but the boot menu gives me the following choices only:
Windows boot manager (this gives me Win 8)
UEFI device (type 4)
UEFI device (type 6)
Is there any way I can boot Win 7 using the old drive? If so, how? Once Win 7 is working I don't mind getting rid of Win 8 but I don't want to risk having no OS.
If I can't use the old drive, how do I do a dual boot install of Win 7 without risking the old OS? Can I use the licence from my old installation? (I will be throwing away the old laptop).
 

Answer:Roll back to Win 7 on a new laptop with UEFI

first check with pc manufacturer that you can find drivers for win 7 for your model machine.
if not backward compatible stay with win8 and install http://www.classicshell.net/

Hello all,

I have a Lenovo B575 laptop that is not UEFI capable; however, I have downloaded the x64 Win 8.1 ISO, burned it to a bootable DVD and a bootable USB drive and tried installing Windows 8.1 using a boot from DVD and also a boot from USB drive, and neither method has resulted in a successful installation. The root cause of the installation problem is that Windows 8.1 is intent on creating an EFI partition structure on my non-UEFI machine. So, I end up with a 300MB Recovery Partition and a 100MB EFI Partition which doesn't work well on my machine. Now, during the installation process, I opted to delete all existing partitions and allow the installation to properly partition the hard drive for installation; however, I knew I was in trouble when the machine started hanging during reboots. I can't figure this one out so any help would be greatly appreciated.

Through BIOS on this Toshiba Laptop i am using i was able to boot into UEFI mode. That was it's default setting. But then i decided to to wipe the Hard Drive using DBAN to re-install a new clean copy of Windows10 64-bit. So i installed it then when i restarted the computer to finish it updating it wouldn't boot it kept telling me Media Device: Fail. So i changed UEFI to CSM / Compatibility and it booted but now it won't boot in UEFI mode at all. Why won't it?

Also i reinstalled Windows 10 using a Disc.

Hi I have tried everythin with this I am trying to install another os on my laptop which has both uefi and legacy.I get the error cannot install because of gpt.
I go into bios turn off secure boot, keep uefi , and try to add option for dvd drive because no option is there for it since I am using a dvd. No matter what, no dvd option is made or comes up.
Should I just convert the whole disk to mbr? Will i lose anything?
Is there a fix for the dvd bootup problem? Thks

Answer:Roll back to Win 7 on a new laptop with UEFI

You have no argument from me - Win7 vs WIN8! The problem you will have trying to boot WIN7 from the old drive is that the new laptop has totally new hardware and new drivers required. If you can get the new drivers for your model, you MAY be able to get the old O/S to boot, but it likely will be recognized as an 'illegal copy.'

If the brands are the same, I have been told by MS 'friendly' customer service that it is frowned upon to do this, however if the old system is being SCRAPPED (not sold or given away) you are on shaky but likely legal ground. OEM licenses are issued to manufacturers, who then install them on the product. Does the manufacturer offer a downgrade option? Many still do due to the slow acceptance of WIN8.x. I'm assuming that no alternate WIN7 installation media came with the laptop? Usually this is an indication of whether a 'downgrade' is offered. I'm still seeing many new machines that still come with an OEM WIN7 installation set. If so, then you are golden!

Better bet is check with the vendor, or best the manufacturer and ASK if they offer the option!

Good luck!

Hello all,

This is my first post. I am a Windows 7 user and now (against my will) Windows 8.

I bought an ASUS N76 laptop pre-loaded with Windows 8 so these are the new generation n76 series. The old ones come with Windows 7. Anyway...

I attempted to boot a Windows 7 ULT 64 install DVD but the install hangs on the Windows logo/flag. So...

- Windows is loading files is shown and hidden
- The animated Windows logo appears and then it just hangs....go figure

I have no idea what is going wrong. I went into the UEFI setup and the only option for my BR is EUFI boot.

I also added a "boot option" asking the EFI to boot "efi\microsoft\boot\boot.efi" or "\efi\microsoft\boot\boot.efi" but when selected (from Boot Override), the screen goes blank for a few seconds, the BR starts spinning and I am thrown back at the EFI so it looks like it cannot find the file. For path, I selected the BR device and at the end has a "\".

I have secure boot disabled. (yep, I have an option for that). So now I am left empty handed and I am stuck with Windows 8. I even put in a brand new SSD hoping I would install W7 on it but I can't even start the setup!! Argh....

I am very experienced with MBR and BIOS but I am a complete newbie to UEFI. I don't know what is going wrong and why the setup hangs....Ther... Read more

Trying to understand handshaking between UEFI & Win 7. Have Win7 Pro sp1 64 installed on SSD, mb=Asus F2A85-V Pro. Example: boot to flashdrive to do Acronis backup of SSD; remove SDD, insert spinner; boot again to flashdrive to do Acronis restore to spinner (to test backup); remove flashdrive, boot to UEFI, set UEFI spinner as default, save & reset; spinner starts boot (#1), Win logo shows briefly, reboots (#2) and shows Win repair/normal screen; choose normal; Windows desktop shows; new driver is loaded for spinner and asks for reboot (that part I understand); reboot (#3) starts and again briefly shows Win logo before yet again rebooting (#4) to the Win repair/normal screen; again choose normal & all is happy. But then I remove the spinner, insert the SSD, and have to go through the whole deal again. Why so many reboots?

Similarly, if I change any hd/flashdrive configuration, my UEFI boot selection is lost & I have to reset it again - sometimes with the multiple reboot scenerio, sometimes not. Sure wish I could force that the UEFI selection stay there as long as the selected drive is installed.

Answer:UEFI boot keeps changing; UEFI/Win7 handshaking confusion

Hello and welcome diana look I am having a little difficulty in following the train of the thread.

Now do you mean you just backed up the SSD to a USB stick ? then tried to transfer that USB stick back up to the spinner? If it was just a back up then I don't think it is going to work because it is only a backup.

To make the spinner the boot device I would be cloning the SSD to the spinner. I wouldn't mucking around with sticks as I cannot see why that is necessary.

And my question is this related to my switch between UEFI and NON UEFI device or that doesnt matter?

Answer:Windows 10 Automatic Repair - switching between UEFI and non UEFI devi

First of all, you dont need to change the boot priority in order to boot from the USB. Use the "Boot Menu" key for this purpose.

In a UEFI system, the disk should boot as a UEFI disk.
If you load the defaults in the BIOS, does it boot back to the SSD? Let us know.

Good day!I have the laptop possibly mentioned above, I did make a recovery USB in case anything would go wrong. My warranty has expired and I am not a newbie to computers, operating systems and such. I got sick of windows 8.1 on my laptop not being able to run old games, so I thought that I would have to install either Windows 7 or XP.I tried Windows 7, with USB stick and then with an external USB DVD Drive... None worked, because I got a "Load Driver" message, where it looks for the CD drivers (of course it doesn't have any). The BIOS barely has settings to enable CSM, Secure boot and to change the boot order, no other technical stuff that would help me proceed with my installation. The CD isn't corrupted, nor the ISO, because I do have an original key to use, so I am not pirating anything. Windows XP, also original, won't continue setup after loading the file acpi.sys, because it will show a STOP error screen about it. As mentioned above, I do not have a good BIOS to change ANY settings needed, HOWEVER the BIOS tells me that CSM can be enabled for INSTALLING WINDOWS XP OR OLDER OS. I cannot go any further than this by any meanings, but I am asking you if is there a compatible BIOS that I can flash so I can change more settings in order to install my desired Operating Systems. Regards,MettleSphee

Hi
I have a laptop which came with pre-installed windows 8 pro. BIOS has UEFI. I never liked windows 8 seriously. I tried using it more and more to get used to it but simply i couldn't. I am thinking to get rid of it and install windows 7 SP1 on it.
I just wanted to ask, will i be able to install it and will it work normally or will it make problems?

Specs of laptop are:
core i3 4010U
Ram 4gb (single module)
HDD 500gb ( C drive 60GB)

BIOS has UEFI (not sure what it is and what it does, i just know it is new type of file system for advanced OS) and also there is some kind of protection lock in BIOS to prevent installing other OS but i managed to unlock it from BIOS settings.

If i install win 7, will it work properly?

I have been procrastinating for the longest time, but I really need to get around to formatting the hard drive of my Asus laptop and installing a copy of Windows 7 on it, as Windows 8 has done nothing but irritate me since I acquired this laptop. Now I am not stranger to formatting drive c and installing Windows, but this will be the first UEFI computer I have to do it on. UEFI is a really screwy way of handling BIOS and I am not certain if this is going to cause me any problems when I attempt to replace the OS, so I would like a heads up on potential problems that might crop up before I attempt to format the hard drive.

Does anybody here have experiencing formatting and installing a new OS on the UEFI computer? Is there any advice you can provide or hazards you can point out before I get started?

Thanks for the help.
 

Answer:Formatting and installing Windows on a UEFI laptop

The issue will be to control the BIOS - - that's where the UEFI boot is enforced.
My reading suggests, that there is no option to disable UEFI if it is active (otherwise, there's no point to UEFI at all).

*IF* your bios can disable the UEFI option, then you will be

'home free' to reformat (even at the lower level rewrite of every sector to wipe the BOOT sector)
install per your own background/experience

Now when I come back to it, open the lid and begin to startup from hibernate state it gets hung in the bootup and will not proceed. I have tried holding the power button to shut down and then restart -- no joy -- comes back to the same hung screen. Have tried holding various escape keys with startup -- no joy -- back to that same hung screen.

I am not sure if this subforum is the right place, if not, pleases help me transfer to the right forum...

I recently just build a new setup with Asus P8Z77-V LK, this motherboard comes with UEFI boot and legacy BIOS boot support.

So I tested install windows 7 in both mode, and I didn't find any advantage of UEFI consider it is a new technology been promoted quite a lot for recent years.

The benefit I found is: a graphic BIOS setup, which is useless to most users if you don't OC. Even you did, I still find using keyboard to navigate through the menu is much easier than mouse.

Faster boot time? very negligible, could be 31 seconds compare to 28 seconds. As I timed use my stopwatch, the value could include a few seconds human error as well.

Support boot from > 2.2TB HDD? nowadays most user use SSD as boot drive so this really doesn't matter.

GPT disk partition? don't see any benefit here compare to legacy MBR...

Anyone can enlighten me what is the advantage of UEFI here?

Thanks a lot!

Answer:What's the benefit of UEFI and install Windows in UEFI mode?

Thanks for adding information about EFI BIOS which present a problem for many during installation and repairs.

For this reason alone, I would advise disabling EFI BIOS in BIOS boot order or choosing Legacy BIOS in BIOS setup, installing normally to an MBR disk.

Wiping a HD already formatted as GPT disk with Diskpart Clean Command can clear the way for it to install as MBR. Sometimes it also takes runnning the command "Convert MBR" to change disk from GPT.

Hi all,

Currently having a wake on lan issue with a certain computer.

The machine is setup correctly but the windows boot information is stored in a 100mb UEFI partition, and when the computer wakes on lan, it will not boot windows, just sit at a blank screen.

When it wakes on lan it is trying to boot from the legacy device (same blank screen happens if you choose to boot from it from bios)

ive tried updating the bios but no luck, all settings seem to be as they should be.

Is there some trick to get it to load the UEFI MBR, or is there a safe way other then reformatting the machine to move the MBR over to the legacy device itself?


Thanks for any help.

Answer:Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup to enable Legacy BIOS. Next check BIOS Boot order for an EFI Boot Disk: remove it, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed here.

At first installer screen Press Shift + F10 to open a Command Box, type:

DISKPART
LIST DISK
SEL DIS 0 (after confirming Windows 7 target HD #)
CLEAN
CONVERT MBR
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

Yes. This is how I do any OS tests\'dual boot'\experiments etc with zero chance of damage to the original boot OS\hd. Am keeping a bunch of old HD's for the purpose. The downside is the slight risk for some mechanic\connection problems, just be careful, remember to power down! So if you don't find it troublesome to switch HD's, IMO go ahead and try that route.

Hi, I understand we can't boot a CD with UEFI but why USB is also not bootable? There is no USB option appear in the UEFI boot menu, only internal HDD appear on the boot menu. FYI, my USB is bootable, there is no problem booting the USB after I have changed the boot priority to Legacy. The reason I hope to get it done using UEFI because I heard UEFI boot faster when system startup, although I am not sure what is the main difference between UEFI and Legacy. Please assist further. Thanks PS: Secure boot is off and USB boot is Enabled with UEFI. Bios already upgraded to the latest version, A8CN54WW(V3.07).

Hi,
I have a MSI GE62 2QD Apache notebook equipped with 1TB HDD and running windows 8.1 core edition in legacy mode. I've recently installed a new m.2 SSD to this system and willing to install windows 10 on new ssd with uefi enabled.

First thing I want to know is the existing HDD is formatted for legacy (MBR) and if I change bios mode from efi firmware to uefi and continue installing windows, still the data on my HDD is accessible through the new uefi enabled o/s in GPT SSD?

Secondly I also want to delete "C" drive entirely in the current HDD as I want my new windows installation on SSD to be in "C" drive. Is this possible in the wizard after changing bios mode to uefi ? I want to make sure that non of my data in other partitions of the HDD is getting deleted.

Thirdly is it oky to have GPT and MBR formatted disks in one system? Will it cause any performance issues later?

Please help. Thanks in advance.

Hi and welcome to the forum

If you open Disk Management it will show you if there is an EFI System Partition on your current HDD

This forum is so much of wealthy info and thanks to you all for helping folks like me.

Computer:
New Lenovo Z580 Laptop with UEFI and Windows 8 Preinstalled

What I did (did many things but this is what I remember):
1. Tried installing Ubuntu, lost partitions and Windows didn't boot either

2. Recovered some of the Partitions using Minitool etc but all the Windows files were lost

3. Downloaded Lenovo One Key Recovery ISO (OKR8 ISO) and installed it. Now the one recovery seems to work - at least the screen comes up but there is an error when I tried to do recovery - error code 0xe0ef0050

4. Created a Windows set up USB using my friend Enterprise DVD and overwrote the Install.wim file using the Install.wim that I got from the recovery partition (had to split the image into swm files) but it didn't work. It said the product key doesn't match with the image (I didn't enter any product key anywhere)

5. Tried applying the image of the install.wim that I got from the recovery partition using DISM but it didn't work.

What I have now:
A USB Recovery Disk
The OEM Product key that I got using rweverything
A Windows 8 enterprise edition DVD from a friend
Install.wim file (around 8.9GB) that I recovered from the PRB_DRV partition. In fact I have all files from that partition intact and stored in my other computer.

I have spent more than two weeks in fixing this. I'm trying to avoid spending $50 for a recovery disk from Lenovo. If it comes to that I'll rather buy a fresh copy of Wind... Read more
