Acer Recovery DVD Won't Create 100MB System Reserved Partition

Question: Acer Recovery DVD Won't Create 100MB System Reserved Partition


When I first purchased my Acer AspireOne D255 back in 2010, I immediately deleted Windows 7 Starter and installed a dual-boot of XP Home and Ubuntu. However, recently I decided that I want Windows 7 back on the Netbook, so I ordered Recovery DVDs from Acer.

I would like to set up an encrypted dual boot between Windows 7 Starter & Kubuntu 12.04. I found a great tutorial online explaining how to do this:

[not sure if I'm allowed to post links to other sites]http://

Problem is that the tutorial won't work for me because I don't have the 100 MB System Reserved Partition. I want to follow this particular tutorial because it's very simple, and it ensures that if I switch to a different Distro later I won't have to reinstall Windows 7.

Now I did successfully follow the "Option One" instruction here to use Disk Management to create a System Partition:

System Reserved : Create Using Disk Management

All this accomplished however is creating a small partition that is not active, and certainly not at the front of the disk, and definitely not set as a System Partition.

Please help! I've spent way too many hours / days at this trying to figure this out on my own.

Edit: I have been using the "Disk Utility" in a Lubuntu 12.04 LiveCD to partition the drive...

Preferred Solution: Acer Recovery DVD Won't Create 100MB System Reserved Partition

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: Acer Recovery DVD Won't Create 100MB System Reserved Partition


You should first install Windows 7 in the vanilla fashion - that will create the 100MB System Reserved partition and the usual System partition (usually C)

Then follow the tutorial you linked. Be very careful with Truecrypt. Create a backup of the volume header : see STEP 3 here:

I'm running XP Home SP3 and Win7 Pro 32 bit in a dual-boot setup. I use Macrium Reflect to image the entire boot drive.

Looking at the graphic for Disk Management in both XP and Win7 (shown), I don't see the 100MB System Reserved partition, even though the numbers add up as shown. Shouldn't that 100MB partition be visible? Where would it be located? Between the two main partitions D: and C: ?

Answer:Where's my 100MB System Reserved partition?

If the drive was already partitoned when you installed Windows 7, it will not create a Reserved partiton.
It will put the boot data, etc. on the first partition it sees.

I'm in the process of swapping out an HDD boot drive for a new Crucial M4 SSD, and discovered that a 100MB partition I created for "system reserved" files got squeezed down to 79MB by the Acronis cloning software I used. The SSD booted just fine with the smaller partition, and my offset is set to the recommended 1024. Is there any reason I need to be worried about a system reserved partition that isn't exactly 100MB?


Answer:Win 7 System Reserved partition smaller than 100MB?

Short version, no.

Does no harm to the system, but please post a screenshot of you partition manager open.

Here is an earlier thread about the same case, if your partition is unassigned as well than you can 'remove' it or just leave it alone.

I am gonna do a format reinstall of Windows 7 and I noticed this partition which I believe was created when I first installed Windows 7. Should I just leave it there or can i delete this partition when I format reinstall Windows? Thanks.

Answer:Disk 0 Partition 1 System Reserved 100mb

Yes, and yes. I would normally leave it, but if you delete it the Windows 7 install should just recreate it. It's where Windows 7 likes to put the MBR (and, I've read, some credentials information).

I did a standard Win7-64 installation on a 128GB SSD and have no problems. My question is, can I merge the 100MB System Reserved partition that the Win7 Installer creates into my normal boot partition. Right now that 100MB is just wasted space and I'd like to get it back into use.

I have MiniTool Partition Wizard and this screen shot shows my current configuration.

My concern is that my system won't boot if I merge the 2 partitions because the new partition starting place will be different from where it is now, and I'm not clear on what to do about Boot Manager or how to get it to point to the proper place.

I do have the MiniTool boot CD and I have verified that this works OK, but I can't find any info on whether or not trouble will happen if I merge the 2 partitions on my boot drive.

What is that "System Reserved" partition supposed to be used for anyway?

I see that one can pre-partition and format a drive to prevent Win7 from creating the recovery partition. My question is if I use Shift+F10 to bring up the command prompt and use diskpart to partition and format the drive, will the partiton table still be aligned to the 4K allocation desireable for SSD performance?

Plus, it seems the 100MB partition somehow messes up any attempt to restore an image with the Win7 built in imaging tool.

Or do the SP1 discs not force the install of said partition anymore?

Answer:Recover windows 7 100MB System Reserved partition

Make sure the partition is formatted primary and set active. All other partitions not active.
Make a system repair CD (or download an ISO) from someone's PC. It is in the Backup & Restore screen.
Run the Startup Repair 3 separate times. This should rebuild your system reserved.

Hilast night clean installed windows 7 pro and noticed that system reserved partition is created with 100MB. Then upgrade it to windows 8 pro and finally updated it to windows 8.1 pro.
After complete installation of windows 8.1 pro and noticed in computer management that still system reserved partition is 100MB. whereas if in case i did clean installation of windows 8 pro then system reserved partition will be 350MB.My HDD capacity is 2TB and i have nearly 1TB of unallocated space. C drive is 200GBTherefore i would like to increase my system reserved partition from 100MB to 350MB.How to increase system reserved partition from 100MB to 350MB with step by step ?What is the advantages of allowing 350MB to system reserved partition in windows 8.1 pro?

Answer:Planning to move system reserved partition from 100MB to 350MB ?

On a Win 7 clean install the system reserved partition contains the boot manager and configuration files, with the system recovery files placed on the OS install partition.
On a Win 8 clean install the system recovery files are placed in the system reserved partition, hence the need for a larger partition.
When an upgrade from Win 7 to Win 8 is performed the system reserved partition is retained at its current size and with the same file placements.
I would be inclined to leave it alone.  If you start moving files and get it wrong, you could end up with a non-booting system.

I'm running Windows 7 Home 64bit on a Compaq Presario CQ61 laptop.
I have a 120GB SSD drive (C) with only Windows operating system and program files.
I have a 320GB HDD drive (D) in place of my DVD drive which holds all my documents.

Following a foolish adventure with Linux which forced me to re-install Windows,
I find my 320GB drive partitions are no longer optimal.

When setting up Linux I reduced the size of my documents partition to provide for Linux partitions.
When re-installing Windows, the installation setup a 100mb System Reserved partition immediately after my documents partition. This leaves a 42GB unallocated portion of my HDD.

I understand that I cannot delete the 100mb System Reserved partition as that is required for boot files etc.
However, I would like to move the System Reserved partition to the end of the HDD so that I can resize my documents partition using the 42GB of unallocated space.

Partition Wizard does not allow me to touch the System Reserved partition, how do I move it?

Thank you,


Answer:Moving 100MB 'System Reserved' partition to regain unallocated space

"system reserved" is not on the win7 physical drive!! Since you have one 1 OS... It is very good thing to move it to same disk as WIN7. even better merge the boot filles and boot menu to the C-drive . Wanna know how?

Answer:Will it use the same system reserved partition or create a new one?

Hello, what you do when you clean install is under your control. You want to install to unallocated space on your disk, so you delete unwanted partitions.

A normal set of partitions for an EFI-based installation is
Recovery (450Mb), System (16Mb), Windows, EFI (100Mb).
Sizes may vary a bit.

It seems that when upgrading (e.g. 1511 -> 1607) Windows uses some 500Mb of unallocated space to create a second Recovery partition. The old one is redundant, as I understand it. Perhaps that is left to support reverting to the old build. I've not researched it.

The Windows partition is the same one on upgrading. You need about 20Gb (for Windows.old) + 10Gb spare.

I have two drives in my computer:

Drive 1 (contains Windows 7 x64)
Drive 2 (contains the 100MB reserved partition)

I want to remove Drive 2 and move the reserved partition to Drive 1.

I made a 100MB partition on Drive 1 (shrunk it first). Then I shut down the computer and disconnected Drive 2. Then I inserted my Win7 DVD, started the computer and selected "startup repair". According to the log, it did repair something (I even let it run 3 times). But when I remove the Win7 DVD, the system won't boot. Only when I re-connect Drive 2 (which still contains the 100MB reserved partition), it will boot.

What am I doing wrong? Thanks!

Another question. Do you really want to keep "system reserved"? It's used for:Bootmanager and bootmenu
Bitlocker encryption.
You definitely want bootmanager and bootmenu on a separate partition?

Sometime ago I installed a second, larger SSD on a Dell XPS8700 but due to my lack of attention I reinstalled Win10 without a System Reserved Partition. By the time I realized what I had done, I had installed too many programs to start over and decided to just live with it. So far there have been no problems. Now I understand that the next major Win10 update, in early 2017, may not install without an SRP. While I could always start over with a clean install, the thought of reinstalling a huge number of programs along with configuring them is daunting. It would likely take at least 4-5 full days of work, something I?m really not up to at this point. So I?m wondering if I might be able to avoid this by the following:

Do a fresh install, after running a current backup of all the existing partitions, with the correct partitioning thereby creating a correct SRP. Then reinstall my previous OS partition from a backup copy. I realize that two sets system files would exist, one on the newly created SRP and one from the restored C-Drive. Which set of files would be used to boot from the newly created SRP or the OS partition? If it successfully boots than I suppose I could remove the duplicate files from the C-Drive. What concerns me if that there will be registry entries that would be incorrect and it would fail to boot after the C-Drive restore.

Do you think this would work? If not then is there another way I could correct the partitioning?

Answer:Create a System Reserved Partition and keep original OS

When you talk about System Reserved Partition, I assume you installed Windows using MBR partition scheme. All you need to do:
For Windows 10, The System reserved partition size is 500MB so:
Use Magic Partition Manager Software to shrink C drive and create a 500MB partition, format as NTFS in front of C drive.Use EasyBCD 2.2 - Neowin to move the BCD to the newly created partition, rename it as System Reserved and remove the drive letter from this partition.

NOTE: use the drive letter assigned for 500MB partition istead of C as shown in screen shot.

Hi all!

I've got 2 Hard Drives in my laptop. 500GB and 80GB.

I want to install win 8 on entire 80gb of 2nd HDD. When I'm trying to create partition installer don't create system reserved partition. It's weird because I've got previously win 8 with 350MB system reserved partition on this HDD but I format them (hdd).

Now installer don't create system reserved (even after [diskpart - > clean])... is it normal? Should I install win 8 without system reserved? Is it necessary for something?

Answer:Why win 8 installer don't create System Reserved Partition?

The installer probably grabbed another active partition to place the bootmgr. If your 500GB disk is disk0 and the 80GB disk is disk1 (in Disk Management), that is what most likely happened.

Hi, I'm trying to recreate win 8.1 pro system reserved partition on my ssd. Initially I installed windows on my ssd (c: ) and windows created the sysres partition on my unformatted hd (without telling me anything). After some trouble I managed to be able to boot from ssd directly without going through the sysres partition on the hd. Now if possible I'd like to recreate the sysres on the ssd (by disconnecting my hd so that windows has no other options than creating this on the ssd). If a try a system refresh it tells me it would wipe away all my user installed apps. Can you tell me how to recreate that partition on my ssd without messing things up? I googled for this but I can't find anything useful.

Here's the reason why:

Now, back to your question:

Make sure you mark this disk ActiveMark Inactive the other Disk that you previously had the reserved partitionOpen the BIOS and set first boot priority to the SSDreboot. <===== if it does not boot, you might have to do a startup repair.Once everything is working, remove the drive letter Z: so that the reserved partition is hidden.

I have a bit of a problem. I recently got a new SSD and configured it to make it my boot drive. I kept my old installation on my hdd and also made a new partition on that device to hold all of the program files, data, etc. Whenever I was finished installing all the programs that I had on my old setup on my new setup and had transfered all necessary documents, I figured it was time to remove the old partition and expand the new data partition to fill the drive. I used gparted to delete the old one and expand the new one.

For some reason, whenever I installed windows 7 on my ssd, it never created a system reserved partition. Everything booted up fine. After deleting my old partition, my system now fails to boot up and gives me the message "BootMGR is missing. Press CTRL+ALT+DEL to restart". Clearly, my computer is now wanting a system reserved partition.

My question is, how do I create a system reserved partition AFTER Windows 7 has been installed?

I have already tried startup repair and all of the bootrec.exe commands, but none of them seem to work. Could someone help me out here?

Answer:create a system reserved partition after install?

The system reserved partition was not created because setup found an active, formatted partition to install to. That is normal, and is certainly not causing your problems.

First, make sure the SSD is set to be the first to boot in the BIOS. That alone may solve your problem, but if not, run a startup repair. I'm almost positive that will work.

I restored Windows 7 Home Premium (64 bit version) on my PC and I used Easeus Todo Backup v4.0.0.2. to do this. I restored the hidden reserved partition and also the Windows partition (my C: drive). However, the restoration altered the size of both of these partitions. It has reduced the reserved partition from 100 Mb to 99.7 Mb and I'm guessing it must have increased the C: partition and used the 0.3Mb reduced from the hidden partition (I can't remember the original size of my C: partition)?

Will the reduction in size of the reserved partition from 100Mb to 99.7Mb have any implications? Does anyone know why this should happen and should I use a partition manager to put it back to 100Mb?


Answer:100Mb Reserved partition reduced in size by backup software

No need to worry.

Go to Disk Management and see how much of the 99.7 Mb is used.

Hi All,

Somehow I have ended up with two system reserved partitions. I enclose a screenshot of my disk management screen.

Disk 1 is my primary Win 7 boot drive... Because of this I am assuming that D:/ which is the system reserved partition on that drive is needed.

However, disk 0 is just a backup I disk I use for data, music, videos etc..etc.. but somehow it seems to also have acquired a 100MB system partition (may be due to the fact that I used to have a dual boot linux setup).

Anyway, I am thinking that I can probably delete G:/ the 100MB partition on that drive. The only thing that worries me is that it's listed as 'active' as is D:/...

Also, should my main C:/ be made 'active'.

Help appreciated. Thanks.

I have a brand new SSD that I just installed Windows on using an Ultimate Upgrade Disk and followed the "Clean Install using an Upgrade Disk" tutorial on here, and also the "Relocate Users folders during Windows 7 Installation" tutorial after Windows was actually installed.

According to the first tutorial the Windows install SHOULD have created a system reserved partition since the whole SSD was unallocated space, yet it did not.

Now I DID have Ubuntu installed on another HDD which had a partition marked as Active, and for some reason one of my other drives was also marked as Active, since I reinstalled Windows I have now removed the Ubuntu Partitions and I have now set the other drive that wasn't meant to be Active, as Inactive, and set my "C" drive which is marked as Boot, as Active.

However before I go about reinstalling MORE software (so far just Flash Player and Antivirus software), I would rather format C and reinstall again if it would properly give me the 100Mb System Reserved Partition that is so useful when Windows breaks itself.

So can someone tell me by looking at the provided screenshot of Disk Management whether another fresh install will actually create the 100Mb System Reserved partition that I want on my drive.

Answer:Lack of 100Mb System Reserved

Your system files got written to Disk 1 because you did not unplug all other drives and it was marked active when you did the install.

You do not need a SR partition.

Re install windows and this time unplug all the other hard drives, if you want a SR partition just delete the drive to unallocated space.

Hello guys, I'm new to this forum.

I need your help desperately:
I had system file corruption and had to reinstall Win7. The problem is that I formatted the 100mb partition.
I know this is an important part of the system and want to have it back. It complies with size (100mb) and position requirements (the first partition).

There are a lot of post dealing with getting rid of it. I want the opposite. Howw do I do it?
Now, there are some constraints: I cannot delete the entire disk because I have a Linux installation in another partition. And if I delete the 100mb partition to try and lure Win7 into creating it, it'll change the partition table and my bootloader won't be able to locate Linux.
Can you help me please.

Answer:How do I re-create the 100mb partition?

Be aware that having GRUB on the HD can corrupt Win7 at any point so this may not work although it is proven to create the SysReserved partition by tests done by BareFootKid and has worked for others:

Boot the Win7 DVD Repair Console or Repair CD, access a Command line to mark the 100mb partition Active: Partition - Mark as Active

Now boot the DVD repair console or Repair CD, accept any offered repair. When Win7 doesn't start, boot back in, click through to Recovery Tools list to run Startup Repair up to 3 separate times with reboots until Win7 starts. Startup Repair - Run 3 Separate Times

If this fails you can try doing a partition-specific wipe of 100mb, in case it has been corrupted by GRUB, using free Partition Wizard bootable CD which can also Modify>Set as Active. Then run Repair x3. You can also use PW CD to shrink Win7 to create the 100mb if it isn't already created as it appears from your post.

If it won't work then it is likely because of GRUB corruption on the HD, which is why it is best to Dual Boot Linux on another HD via the BIOS to avoid GRUB corruption of Win7.

Hi guys. First post here so take it easy on me, haha.

I installed Windows 7 Enterprise 64-bit edition on my new Lenovo laptop. I captured an image of my machine and deployed the image to several others. Now, we want to start using Bitlocker. However, there is no "system reserved" partition, you know, the 100MB one that Windows automatically creates during install. Turns out that Bitlocker NEEDS this partition.

I can manually create this partition, but I don't think it's useable by Bitlocker. Regardless, I tested this. I created the partition (200mb after shrinking primary partition), rebooted, and ran the manage-bde -status command. There is another drive listed but it's unusable.

Hi guys,
I have had a look here for instructions using diskpart to create an MSR partition. A while back I had to move the MSR partition around, which caused it to get corrupted and I was unable to fix it. PC has been working fine until trying to upgrade to windows 10. Now, I get an error which complains about the system reserved partition, which I know is not as it was initially.

After deleting the volume in diskmgmt, I check the partition layout:

DISKPART> list partition

Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 System 64 MB 20 KB
Partition 3 Primary 23 GB 193 MB
Partition 4 Recovery 5400 MB 23 GB

and then run

DISKPART> create partition msr offset=65

Virtual Disk Service error:
There is not enough usable space for this operation.

I need help to recreate this MSR or somehow repair it (alternatively just let it upgrade to windows 10)


Answer:Recreating Microsoft Reserved (system reserved) partition

Are you sure its MSR and Not EFI ?
otherwise you'll have to use a partitioning manager software to move your partitions around to get enough room at the beginning of the drive for this partition to have enough useable space?

ok, i have an msi ge60 ond, and it has a recovery function with the F3 key at startup. i'm wondering if this is tied to the 11GB partition on my hard drive? or to the 100mb partition?

or is anything is even on those partitions? look at the the "free space"....? looks like nothings on there. i just want to know if there is anything on there so i can merge all the partitions into one if not (i think i'm a little OCD when it comes to this hahaha).

Answer:whats on my recovery and 100mb partition?

The boot critical files needed to start windows are on the 100mb.

The files needed to restore/recover your pc are on the 11gb.

Answer:how to create system recovery in other partition in fresh installation ?

You would have to partition your main Hard Drive into 2 drives (Drive C: and D: or purchase another HDD) Once you get your C:Drive working perfectly and have all the drivers, updates and software you like installed, then you would Clone your C: drive to the D: drive using Ghost, Acronis or XXClone Then if your C: partition has a problem you can restore from your D: partition. Of course if the whole hard drive takes a dump, this won't help you, unless you had a separate HDD.

Hello, I have started the installation process of windows 7 on a clean 1 TB hard drive. In order to ensure expediency of the read time of my primary drive, I choose the custom installation. When I did I partioned the drive as 250GB & 700GB. Hoever it also created a 100MB system partition on its own. It never did this in Vista. Is it suppose to do that?

Answer:Installation: Partition - why a 100MB system partition

100mb SysReserved contains the boot manager and the same tools which are on the Install or Repair disk Repair My Computer console, however this partition makes them available on Advanced Boot Tools via tapping F8 at bootup. System Recovery Options

It can be removed but should not be unless it creates a conflict. It will require marking Win7 active and running Startup Repair up to 3 separate times with reboots to recover after removing it.

Hi, so first of all i'm going to tell you that i have two hard drives one is WD Caviar Black 1TB (primary) which is partitioned in two "Local Disks" 150GB for the OS and 781GB for games and other stuff and the secondary hard drive is WD Caviar Blue 500GB which i had partitioned also in two local disks but after of using for a long time it seemed that it was in its end but after searching online i found that it had some "soft bad sectors" and those can be fixed by doing a "Low Level Format", so i downloaded "Active Kill-Disk" to do it so i did it successfuly and after it finished i didn't get again the "local disks" in My Computer but in Disk Management yes but this time like a "Unallocated space 460GB" and i went into the Windows 7 format process to format it and make a new partition so the process of "paritions" in the windows 7 setup was like this:

Answer:windows 7 100MB system partition

You are not explaining yourself very clearly. Try complete sentences following in logical sequence.If you are seeing your system's recovery partiton (probably 'D' drive) in 'Computer' you need do nothing at all. You should ignore it. Do not attempt to open it or save anything to it and it will be there if you ever need it. There is probably a way to hide it again and someone may give you this information, but if not, just leave it alone. The ONLY time you MAY want to do anything to it is IF the recovery partition is from an OLD operating system like Vista that you will NEVER use again. While you are at it, make yourself a recovery DVD which can be used to recover from even if your drive completely fails.You have to be a little bit crazy to keep you from going insane.This site is about helping people, lets keep it that way.

My current setup is Windows 7 Professional on a 64Gb SSD, and my data on a 1TB HDD; I wish to upgrade my data storage to RAID 5 (via Intel Matrix RAID).

Whilst examining my HDD before I make the change, I noticed that it had a system reserved partition of 100MB on it. After a lot of googling, I had determined that this is used for BitLocker and system recovery, and is not (in most cases) necesarily needed.

However I think that my situation may be different.

The complication is that the system reserved partition is marked as 'System' (as can be seen in the below screenshot), and it seems (from changing boot orders) that the OS actually bootstraps from the 1TB HDD (although it resides on the SSD entirely).

Clearly this is non-ideal (unnecessary coupling of data drive to system drive ect ect).

Does anyone have any experience with this, or know how I could safely migrate the System Reserved partition (or just the MBR, as I dont use bitlocker and have the windows install disks) to the SSD?

Thanks in advance for any replies.

Answer:100mb partition on non-system disk

Temporarily unplug the data drive, boot the Win7 DVD Repair console or Repair CD, at first screen press Shift F10 to open a Command Line then use Diskpart to mark Win7 partition active: Partition - Mark as Active
System Repair Disc - Create

Now return to DVD/CD Recovery Tools list to run Startup Repair up to 3 separate times with reboots to write the System MBR to Win7. Startup Repair

Afterwards you can plug back in data drive to delete 100mb in Disk Mgmt, or use free Partition Wizard bootable CD to delete 100mb and Resize Data Partition into it. You can also use PW CD to Modify Win7 to active instead of Diskpart.

I have restored a backup of win7 system disk to a new 3tb drive. It took me a while but now I understand why it wouldn't let me mark the 100mb boot partition to active. Since it's 3tb its a gpt disk instead of MBR. I though win7 could boot from a gpt drive but I can't get it to boot until I can mark that 100mb partition as active. What's the answer?!!

Answer:how can I set the 100mb system partition active on a 3tb drive

I assume you cannot get into windows to use disk management. Hopefully you can get into recovery console. This will help you set the active partition, hopefully thats your issue.

list disk
select disk (your hard drive)
list part
select part (the partition you want active)

then reboot.

EDIT: You can also try fixboot.

An explanation of my PC's hardware first of all. My system has 5 SATA hard drives, ranging from 200GB to a 1TB. I am only using two of them, a 200GB one for the OS and the 1TB for storage (Full). This leaves three empty drives.

Now, I want to create a striped array with the three remaining drives, two 500GB drives and a 350GB drive. Now for my problem. One of the 500 drives has a 100MB BitLocked system partition on it (The windows recovery stuff) and I am unable to include it in my striped array.

In fact here is a screen shot to help clear it all up:

The three red arrows show the drives I want in the Array, and the green star highlights the trouble causer. I already know that reinstalling windows 7 and partitioning the drives prior to this will prevent this partition from been created. But what I need to know is, can I safely remove this partition without causing my system to stop booting.

I'm trying to recover my partition table using MniniTool Partition Wizard. I tried running the Partition Recover Wizard which listed the 2 partitions on my disk i.e. ACER and SYSTEM RESERVED. It also listed the hidden PQSERVICE partition which comes with factory settings. The ACER and PQSERVICE partitions are listed as "Lost/Deleted" and SYSTEM RESERVED is "Existing".

However when I try to select all these partitions so I can recover and keep them all, the status of SYSTEM RESERVED changes from "Existing" to "Overlapped" and I can't select it anymore. When I move to the next step it tells me that it'll have to delete the SYSTEM RESERVED partition.

I don't know if i should go ahead and do so. or if it will just make things worse. What should I do?

Trying to do a clean install and my Windows 7 Home Premium x64 seems to have an aversion to putting the system reserved partion on disk 0. My HP notebook has two identical disk drives. If I boot up the windows install with both drives unallocated and do a custom install, the window where i select the partition for the install if I click new to create a partition on disk 0, it creates one partition on the whole disk. If I do the same for disk 1 it automatically creates two partitions, one for the system reserved. If I try to do that in reverse order by partioning disk 1 first it will still create two partitions on disk 1 (one for the system reserved). It wont partion disk 0 with the system reserved partition.

I tried to install windows with only disk 0 plugged to into the motherboard and that worked when i partitioned the drive during the windows install it created the system partion on disk 0. However once i had windows up in running, I plugged disk 1 (unallocated) back into the mother board and windows woudnt boot up.

I could jsut install windows on disk 1 but ive read that it is better to install it on disk 0.

Answer:Clean install wont partition Disk 0 with system reserved partition

Welcome to the forum.

When you tried to boot with both disks installed, did you go to the BIOS and check that disk 0 was the first in the boot priority?

Hi all.

I don't know about you guys but the extra 100 MB system partition that sometimes gets created annoys me -- I like to have my OS installed cleanly on a SINGLE partition - and even when doing a clean install on a new 1TB disk I don't want to assign any more than 50 GB (Max) to the w7 partition so here's how to fix it without doing a re-install.

( I know its only a single small 100MB partition which is nothing on a 1.5TB disk - but it still annoys me - and its easier to backup and deploy images if they are all on a SINGLE partition).

1) Ensure you have a bootable restore version of your backup software and the W7 install DVD -- you'll need that later.

2) Backup your OS with Acronis True Image / Ghost -- Acronis works fine since you can specify the partition size on restore and change the partition type.

3) Delete the OS partition AND the system partition. You can use something like the Windows install disk - but after deleting the partitions don't start the install.
Other partition deletion software such as GPARTED can be used

4) Restore the OS and specify partition size. ALSO CHANGE PARTITION TYPE TO ACTIVE.

5) Now boot from the Windows Install disk and select REPAIR SYSTEM -- you'll need to do this since the restored OS will be missing BOOTMGR on it.

6) Let repair do its thing

7) Boot into W7 -- now its on a nice single partition.



Answer:Removing 100MB system partition - no re-install needed

or you could simply use the bcdboot command to create the boot manager to the Windows drive and set it "active" using the diskpart command. Although that one only works if Windows is on a primary partition.

Good job on the guide though.

Answer:Is a 100mb system partition required on my data disk?

Well yes I see you are installed Legacy BIOS MBR, fast boot, secure boot and many other features of win 8 and 10 in UEFI GPT mode are not available to you.
I am guessing the 23.9 unallocated partition is for over provisioning, the 100mb partition is MS Reserve partition.
Your Disk 2 only needs the D:\ partition. I'm not sure about the Acronis partition I don't remember having that when I used Acronis???
This is what mine looks like after upgrading from 8.1 Pro to 10 Pro UEFI GPT
I think I can delete the 450mb partition I believe its left over from 8.1 upgrade form 8, since its only 450 mb I don't really need the space so for now I'm not worried about it.

to make the system reserved larger or delete it and make the C partition active,

It sounds like your girl friend had everything prepackaged on the laptop to see that much drive space taken up from the start. Creating a working set of recovery disks would be the only way to work things out for that since you would end deleting the data from it by deletion or trying to reduce the size.

First off, I'm new here so I'm sorry if I am posting this in the wrong section. I appreciate the help.

So that is a screen shot of my disk management screen. As you can see, disk0 and disk1 both have system reserved partitions on them.

Answer:System Reserved in One Partition Vs. Separate Partition?

The question is how did you end up with so large system reserved partition, it's usually about 100 MB. On the other hand it might be a reserved backup partition with all the stuff needed if that's a laptop. Now, if that's a partition you can't just simply put it in another partition. You can format it and merge it with first partition but it will not be a partition any more.

My computer used to have a boot file set on my slave drive, but OS installed on my

Recently a USB gave a conflict to my boot priority and wasn't letting me boot with both my hard drives intact. Solved it by loading start up repair via a win7 disk and "repaired" it.
However, now there's the partition of my slave drive, that is marked as system, active now. Before it was just "unallocated space". How can I "shift" that over so that nothing "boot worthy" or "system active" is part of my slave drive?

Thank you for your time. Please take a look below at the screen shot.

Disk management (right click on My Computer, Manage, Disk Management) should allow you to simply delete that partition if you don't need it. Just make sure you don't need it before doing so. I'd unplug the slave from the mobo and boot the computer to make sure everything is fine without it.

When i am trying to merge those two using acronis disk director ,it says cant merge.

Answer:System reserved partition.

Why do you want to do that? If you move the beginning of your Win 7 OS partition, it won't boot.

It's possible to delete the "System" partition then do a "startup repair" on the OS partition if you want to reduce the number of partitions on your disk. However, you need to leave the then unallocated 100 MB as it is.

Edit: Keep in mind that the relative sizes of partitions are not accurately displayed in Disk Management. In you attachment, your System partition and your C drive look the same size. In actuality, the System partition is only one tenth of one percent as large as C.

I want to know also, but I have not really researched this phenomenon. The reserved partition has something to do with BitLocker AFAIK. I encountered this belief here at SF.

I've looked all over for a fix and have found several methods to accomplish this ranging from "just delete the drive letter" to "don't do it" with things in between like delete the drive letter then re-image the drive or remount Etc. How can I delete the drive letter, bottom line, the simpler the better.

Also, now rhe DVD drive only shows up when there is a disk in the drive, all other times the drive is "hidden". This is not a real issue, I can live with it. The other is very important to me.
Any comments or suggestions welcome.

Answer:System Reserved Partition

Hello Dusty,

Before we recommend anything about the "System Reserved" partition, please post a screenshot showing the full layout of your Disk Management to make sure we'll be accurate as possible. Most likely, you will just need to remove the drive letter.

It sounds like you have Windows set to not show empty drives. Turning this off should sort the DVD issue.

Hope this helps,

Good question ...

100MB is the minimum requirement for a partition as stated here:
System Partition Requirements

"Basic system partition requirements are:
Must have at least 100 megabytes (MB) of hard drive space.
Must have enough free space to create shadow copies of the partition."

I just recently purchased computers for our office. When we booted the computer up for the first time it went through the initial install of Windows 7 32-bit. There is one thing I dislike about per-configured computers -- and that is the multiple partitions they assign the hard drive. Anyways, I will stop ranting about this and get into the question I have today.

There are currently two partitions on the hard drives. One is C: and the other D: (System Reserved). I would not have a problem with this, but System Reserved can be accessed. It is not hidden. On the older hard drives, this partition was hidden. These computers are being pushed out to the public, so I wish to hide this partition. I do not want to delete it, because I am sure that would do harm to the hard drive.

Please help.

Answer:System Reserved Partition


You can go to the Start orb, go to Administrative Tools (it can be accessed thru search) and go to Computer Management. On the left-hand sidebar, go to "Storage" and the 1 sub-category under that. Wait for the disk information to load and right-click the partition you wish to hide, and change the mounting, to remove the drive letter it is mounted under.

Good luck!

Morning everyone, I have a custom PC I built and I was running 8.1 on it. I have to drives a 120gb ssd that had windows on it and I have a 1 TB that had the 350mb system reserved partition and 2 other partitions I had for data and a boatload of free space. I wanted to try and install Linux Ubuntu on the 1tb hard drive. I did a custom install on it because I didn't want it to delete my existing partitions so in the install I made 2 partitions for Ubuntu, after I installed it my 2 data partitions are gone and I don't know what happened with the 350mb system reserved partition. On that disk now is the 2 Linux partitions and a 150mb partition that I can't tell what it is. But now I can't boot into windows, even when I go from bios. My question is in that system reserved partition is that where the bootmgr is? Because I did nothing with the ssd where windows is and I get a no operating system error when I try to boot off it. I just don't know how I can fix that disk if the system reserved partition isn't on it.

Answer:System reserved partition

1) Physically disconnect the 1tb HDD.
Make the Windows 8 SSD, disk0 & first HD boot in BIOS.Also connected to the first Sata port on the MOBO.

2) Then
Mark the Windows 8 SSD Drive ACTIVE

3) then

4) When Windows is booting OK, Reconnect the other HDD, as Disk1.

If you can boot with only your SSD connected, that means the boot loader files are present in your C: partition, and in that case, you don't need a separate System Reserved partition.

I've read here that individuals with a SRP of only 100mb have had issues installing WIN 10 and that those issues were resolved by expanding the SRP from 100mb to 450mb.
Will WIN 10 install if I have no SRP? Will it merely alter the boot files on my C drive?

I'm not certain.

I think your machine will be fine. It's not important where the boot code lives (SysReserve or WinDrive).

For the record though, it appears that a Clean install of Win10 on MBR initialized drives defaults to 500 MB. I have not seen any documentation yet.

If you only have the SSD connected, there should not be an issue when you upgrade. If have other drives connected, the install might use one of those for the boot code - this is not an optimal disk configuration. You want the System and Boot partitions on the same drive. Since your boot code is on the Windows Drive, no problem there.
I'd like to see your Disk Management. If you already downloaded the custom Management snap-in, you don't need to download it again. Just launch dmDskmgr-vd in the location you previously saved it (yes, you can still open the zip folder and launch it from inside)

I have a Windows 7 Professional system whose hard drive was upgraded from a regular 500Gb drive to a Solid State 1Tb drive and the manufacturer's cloning utility was used to move everything over to the new drive.  I was trying to update the system
to Windows 10 Professional but kept getting the error message that it couldn't update the System Reserved partition.  I know the installation process needs at least 350Mb for the process so I started doing research on the best way to extend it. 
Following instructions posted in the Community, I shrank the C: drive so I would have 370Mb unallocated space, but when I went into the Disk Management console to extend it, that option is greyed out.
It was after closer examination I noticed I do not have a partition that is labeled specifically as "System Reserved" and I do not have a stand alone "Boot" partition.  I have one partition labeled Data with no drive letter that
is 100Mb that says "Healthy (System, Active, Primary Partition)", one partition with the drive letter C: that is 931 Gb that says "Healthy (Boot, Page File, Crash Dump, Primary Partition)" and then 370 Mb of Unallocated space.
To get the reserved Windows 10 installed I was thinking of possibly taking that Unallocated space and following the instructions I've read elsewhere, create the System Reserved partition so it would then be 370Mb but I'm not sure just doing that would work

I have just restored win 7 with shadowprotect. I restored the 100mb image to a hundred mb partion and then the other image to a second partion. I remove the drive letter from the 100mb eveything works fine and looks like a window setup but the 100mb part. is not system reserved. I want to make it system reserved how do you do this?

Answer:Windows 7 System Reserved Partition

Hello Wallymagic Welcome to the Seven Forums!

The 100mb system reserved partition is placed there by the Windows 7 installer when that first partitions and formats a "raw" drive, drive with totally unallocated drive space lacking any existing partitions and places the main boot files and boot configuration there(BCD store).

As long as it works the way it is and isn't mounted as a logical drive you should be all set. To see that become labeled as "system reserved" you would either have to name the volume again seeing it mounted or perform a clean install of 7 fresh from the start once the drive was made raw again.

Labeling it that in the Disk Management for example would likely mean reassigning a drive letter temporarily to see that done while unnecessary if left hidden from view and direct access. For a look at just what is seen on it the 100mb boot partition had been previously mounted here and a drive letter selected to show how that looks.

When originally installing Windows 7 Ultimate I noticed it created a 100mb system reserved partition. No probs.

Recently I turned on AHCI in my bios and attempted to do a clean install. This time WinPE did not create a reserved partition and despite creating an 80gb partition to install windows on it said “Setup was unable to create a new system partition or locate an existing system partition.”

Install refused to proceed any further, pointing me to some log files I could not find. I booted from my repair disk and tried to make the partition active, which was already marked as active and tried again. No luck.

I had deleted all partitions on the drive.

So I turned off AHCI and tried again. I missed the "press any key".. and system complained about a "Master boot record error".. I rebooted and tried to do install again. Same issue.

I was able to recover my system from an image I created earlier, but I sure would like to know why the reserved partition was not created, and why windows refused to install. Because I'm going to try again.

I have purchased a new HDD, one that is supposed to be much faster than my old one, which of course has not been formatted. I tried that drive with and without AHCI and had the sasme issues.

Answer:System reserved partition not created

If you have partitions defined beforehand it will not offer the Win7 100mb System Reserved partition. Wipe the HD and it likely will.

There is a way to get out of it during install, by deleting the Win7 partition and expanding the 100mb partition it creates to install Win7 there.

The easiest way to wipe and/or format the HD ahead is to boot into the Win DVD repair console, open a Command Prompt and type:

SELECT DISK # (for Windows 7 disk)
create partition primary
select partition 1
assign letter=c:

Now you are ready to boot back into the Win7 DVD, select Custom install and install Win7 without the System Reserved partition.

If on the other hand you want the System reserved partition, just run Diskpart through the Clean command, exit and begin Custom installation using Advanced drive tools to create New and format.

6)Moved image of boot drive to a larger SSD, expanded the primary partition on the new drive to make the additional storage available.

You've found one of the biggest reasons I despise multi-boot systems, especially if you onl have one hard drive to use.

I'm not sure what I'm looking at, though, in terms of what you want to keep. Assuming only C, D, and E are what you want to keep, I'd just get Partition Wizard and delete the unneeded partititons. Then, you can move C to the beginning of the drive.

My computer came with a 1TB drive pre-installed with windows 7 home premium and no windows install disk. I immediately created the system restore dvd's so at least I have a default copy of windows.

From past experience I prefer to have a smaller drive with windows (which i loaded from the restore disks) and the 1TB as a second drive to hold all my files. Now I see I have a system reserved drive listed which I didn't have before, presumably a partition on the 1TB. Before I do anything stupid I just have a few questions.

Can the system reserved partition even be accessed for an emergency reinstall if it is on the second drive?

Is it unwise to delete the partition if I don't have the original windows 7 boot cd? I do however have the system restore dvd's which seem to work fine.

Can I reformat the entire 1TB drive, or must I delete the partition first?

If I keep the partition, how can I hide it. Traditional means don't seem to work.

I appreciate any help. Thanks.

Answer:system reserved partition on second drive

You can certainly reformat the 1 TB and get the system reserved partition off of it. You may have to use diskpart to do get rid of it.

If you have retail install discs, you don't need the system restore partition anyway--but your situation with only restore discs might be a different situation.

I'd guess you don't need the reserved partition since you have the restore discs, but I'd wait for more detailed comment.

A complete novice of OS but have questions about system reserved.
My apology if questions are not stated clearly -
It seems that most laptops these days come with at least two partitions in the HD.
Partition One is called Win7 OS (or Win8, I assume) and the other "system reserved".
I've heard that "system reserved" is an IMPORTANT partition and CAN HELP restore the system after it crashes (is this correct?).
I recently backed up my whole HD - not sure if the backup software really backed up EVERYTHING (i.e. both partitions or just main WIn7 OS partition) or only the files in partition one ??
Today I obtained a new HD from a thrown-away laptop and I reformated it.
Question 1 -
after/if I copy everything in system reserved to the reformated HD, can it run by itself like a computer?
Question 2 -
if no, what then will be the minimum that I must copy to the reformated HD to make it an operatable HD?
The reason I am asking my Q2 is that the reformated HD is smaller in capacity. Thus I cannot make a system imagery from my current laptop to the new HD, as I have lots of NON-essential programs installed. I would like to just put in the essential minimum in the reformated HD so that I could use the remaining space for other purposes. Google has failed to help me find what I need for this question (perhaps because I did not know what key words to use).
Any help will be appreciated. Thank you very much.

Answer:about "system reserved" in my "E" drive/partition

So let me tackle what you're asking in order

Question 1 -
after/if I copy everything in system reserved to the reformated HD, can it run by itself like a computer?

Yes, and No.... I know that does not help much.  Meaning assuming the old HD and the new HD are the same type.  Right now there are two types of Hard Drives out there.  HDD (Hard Disk Drives, and SSD (Solid-state drives).  Knowing which one you have right now can be a huge factor in knowing what you can do when something goes down.  Also, using the recovery to make a backup is not a good idea, unless you have a good knowledge level of windows header and recovery functions.
Go to this site and for more info on Hard Drives and what you should know.

Question 2 -
if no, what then will be the minimum that I must copy to the reformated HD to make it an operatable HD?

Answer:  In short, nothing at all.  Again I'll explain.  As long as your HD runs and is not physically broken, then almost any computer will recognize and run it.  (think of a thumb drive /USB stick).  Windows runs it even if its blank.  What you are trying to do is Clone your Drives to another HD and use that encase your current HD breaks?  Correct?
While that sounds good, now days you do not need to do that.  That is what the Recovery Drive is for.  Meaning if the Recovery Dive is a separate drive in your computer then wh... Read more
