Why do we need system reserved partition

Hi,
From windows vista and above MS has come up with an additional 100mb system reserved partition. I read about it on several places over the web that, this partition is used for BCD store.
There are several other filse/folders( en-US, cs-cz, ja-JP, memset.exe) inside other than the BCD store, what do these folders keep and what purpose do they serve. Is it mandatory to have them here, as I tried to delete some of them and didn't face any problem
while booting.
Thanks in advance

The System Reserved partition contains boot files, bitlocker files (if enabled) and things needed for recovery purposes. The idea is that, (ideally) this partition is separate from the OS and that a recovery partition is present. If something were to happen
to the OS, you would still be able to boot to recovery (repair your computer) as the bootloader is not in the OS partition. Is it not required to install Windows with that partition.
When a computer boots, it will attempt to boot the first active partition. In the case there are no active partitions, it will attempt to boot the first partition. This is why the System Reserved partition is supposed to be the first partition. On a GPT
disk, it is possible to have the System partition be the second (with none marked active) and the OS will still boot, so I'm sure there is more to it than that, but maybe it gives you an idea.
The directories are certainly not empty. You would need to use the attribute switch to specify system or hidden files in order to see them with DIR.

Why did Windows 7 make the 100MB "System Reserved" partition on my second hard drive instead of the hard drive windows was being installed on?

I have a Dell laptop with two physical hard drives. When I installed Windows 7, I deleted all the partitions on both physical disks. I installed windows and left the second disk unallocated. So why did the installer decide to place the 100MB System Reserved partition on the disk that wasn't being used?

I found the solution to the problem I described above. Here was the approach to resolve.
Install SATA Y-Power cable jumper on one of the SATA connectors. This gives me capability to power 3 SATA SSD drives
Install the third drive.
Start Windows and initialize the new drive. Now I have 3 drives.
Clone Drive C (Drive 0) to the new (third) Hard Drive (call it Drive 2). I used Acronis True Image Home.
Remove Hard Drives 0 and 1
- the current drives required to boot Windows and that have my Images and data
Install the Cloned Drive as Drive 0 and restart
Windows should prompt me (hopefully) to repair this drive after the boot error.
Run Startup Repair on this drive (drive 2) by loading the Windows Media CD and selecting the only drive installed (Drive 2)
If successful, I would have created a Drive that can boot on its own and has my image and data. If unsuccessful, I put back in Drives 0 and 1 and I am back up and running. I this is a zero risk approach.
Here are the results:
Success!
I got the power jumper cable in and executed the steps below. The below procedure worked flawlessly. The loading of the Windows CD took me to a Repair option that sensed a problem with Startup. If failed
to see the Windows installation on the Cloned drive (now drive 0). This was expected. It asked me if I wanted to fix it. I said yes. The system restarted and there was another boot error. I loaded the Windows CD again. This time it saw the Windows 7 Installation
and told me there were Startup problems that needed to be fixed. I said yes again. The system restarted and Windows came right up!
So now I can boot from one drive. I am going to run like this for a couple of days just to be sure. Then I am going to reconnect the other two drives as drives 1 and 2 and figure a way to use them effectively.
Good luck!

Window 7 system reserved partition

why system take 100 mb for system reserved, and what is the use in system reserved.pls explain in detail.

As explained here
http://technet.microsoft.com/en-us/magazine/gg441289.aspx the system reserved partition primarily holds the boot files, and if you use bitlocker then files relating to that are also stored there. In Windows 7 and 8 it's automatically created as part of
a new install, unless you have an existing partition configured on the machine and instruct setup to install Windows to that (rather than letting it create the partition as part of the boot process.
In theory it is possible to remove it as explained here
http://www.terabyteunlimited.com/kb/article.php?id=409 but as you'll see there are a lot of restrictions on whether it can be done, and the contents of that partition need to be moved to the main windows partition before it's removed.
Personally, considering what a small amount of space it takes up (100MB compared to the total disk space of a modern HDD), and the serious potential of breaking your Windows install if you do it wrong I wouldn't bother removing it. And in terms of getting
a clean copy of Windows installed without it in the first place, it seems like a lot of extra work just to reclaim 100MB.

Create System Image FAILURE because of the 100MB system reserved partition that Windows automatically created

trying to run:
Control Panel\System and Security\Backup and Restore > Create a system image
failed. the first attempts produced the error message:
A shadow copy could not be created. Please check "VSS" and "SPP" application event logs for more information. The specified object was not found. Error code: 0x81000019
so I searched around, read several threads from other users encountering the same issue, tried the various solutions suggested, found Volume Shadow Copy and SPP in services and set both to Automatic and started them, and then I tried running Create
a system image again and received a different error message:
Create a system image
The backup failed.
There is not enough disk space to create the volume shadow copy on the storage location. Make sure that, for all volumes to be backed up, the minimum required disk space for shadow copy creation is available. This applies to both the backup storage destination
and volumes incluced in the backup minimum requirement: For less than 500 megabytes, the minimum is 50 megabytes of free space. For volumes more than 500 megabites, the minimum is 320 megabites of free space. Recommended: At least 1 gigabyte of
free disk space on each volume if folume size is more than one gigabyte.
(0x87080119)
according to this, a 100MB partition (a drive less than 500 megabytes) must have 50MB of free space. as you know, Windows automatically creates a hidden partition of 100MB on installation. that partition contains more than 50MB of data and, therefore,
obviously doesn't have the minimum 50MB of free space required by Windows' Create a system image utility, yet the Create a system image requires that the 100MB partition as well as the C drive and the Recovery partition be included (the checkboxes beside each
one is checked and grayed out, so none of the three can be unchecked). so it appears that Windows has designed an installation default (automatic creation and filling of that 100-MB partition) that conflicts with Windows' own Create a system image utility
and prevents it from working.
what is the workaround or solution to this problem. I will be replacing my primary 1TB HDD with a new one and need a way to back up my system to a portable/external USB 2TB HDD and then to transfer the image back to the new internal HDD once it's installed.
for clarification, this is NOT about backing up my files, so please do not reply with suggestions about archiving my folders and documents. my system is set up the way I want it, with all my personalized settings and configurations, all of my software
is installed, all of my shortcuts, saved context menu data, folders, etc. are where I want them and installing a fresh copy of Windows and all my other software and then redoing everything I've done to get the system set up the way it is will take DAYS of
exhaustive, laborious, and time-consuming effort. Microsoft apparently intended to provide a solution by creating the Create a system backup option, but it doesn't work, so what is the solution?

Hi,
In my opinion, about this problem, there is no relationship with 100 system reserved partition. Moreover, according to the error message, it should be the drive which you wanna store system backup image file doesn't have enough space, not 100M system reserved
parition.
System reserved parition used to store system startup bcd file, bootmgr, necessary file of Bitlocker encryption. This drive won't affect system image backup process.
Therefore, please check the shorage drive capacity if it is meet the backup requirements, also you can check Event Log if it identify the problem.

No system reserve partition server 2008r2

we keep getting errors backing up the system state with symantec backup exec 2010/2012. i noticed that disk0 (where c:\ lives) there is no system server partition which symantec wants. the server works fine and there are no issues on bootup or
usablility.
on disk0 there is:
71MB healthy partition (no drive letter or name) (OEM partition)
RECOVERY 3GB (System, Active, Primary Partition)
OS (c:\) (Boot, page file, crash dump, primary partition)
i dont know how this was first built, not sure if it was server 2008 then upgraded to r2. Does anyone know if i need this? Symantec is telling me this is an MS issue.
Thank you,

Hi,
The System Reserved partition is an unlettered system drive that is automatically created by Windows 7, Windows 8, Windows Server 2008, and Windows Server 2012 during a clean installation.
Because all of the contents of the System Reserved partition are hidden, you’ll need to open the Folder Options dialog box, enable the Show hidden files, folders, and drives option, and disable the Hide protected operating system files (Recommended) property.
Please refer to the following article:

Bootcamp Mounts Window's System Reserved Partition

Bootcamp has decided to mount Window's System Reserved partition instead of the actual Windows partition. It was working fine up until this week when I decided to plug in an external hard drive. After I plugged it in and restarted into OS X, the problem started. The real Windows partition does not appear in Disk Utility. I have tried disabling NTFS-3G and booting without the external hard drive but nothing seems to work. Anyone have any ideas?

What do you call Boot Camp anyway?
The 100MB partition is where Windows boots, if present.
And Disk Utility can mess up Windows 7 and NTFS volumes.
Maybe all the problems are from using NTFS-3G of course.
A number of people, myself incl. do not see Windows in the Apple System Prefs control panel (startup disk).
Windows and Mac OS X do show in Windows 7 control panel Boot Camp.
People misuse the name/term "Boot Camp" (as does Apple) as if it was or does things it does not.

MSR Partition vs. System Reserved Partition

I'm new to Windows Server management, and to these forums as well. I hope this is an appropriate forum for my questions. If not, please direct me to the correct forum.
I have a few questions that I have been unable to get answered with my own research. I will group subjects as much as possible and probably create a few different posts.
I have been trying to figure out a few things regarding the partitions that are created when Windows Server 2008 R2 is installed. Specifically:
1) I've seen the MSR on a server partitioned using GPT, and the System Reserved partition on a server partitioned using MBR. Are these partitions the same thing? Are they somehow different, but perform the same function given the partitioning
scheme (GPT vs. MBR)?
2) I know that the initial size of the MSR can vary depending on the size of the disk. Is there a formula for determining how big the MSR will be on a disk of any given size?
3) I know that the partition GUID can vary depending on whether GPT or MBR is used. How can I find the GUID for a partition?
4) Is it a true statement to say that every GPT disk must contain an MSR, and that therefore any disk containing an MSR was partitioned using GPT?
Thanks for any help that you can offer!

Windows 10 upgrade fails with error message "we couldn't update the system reserved partition"

HP and Microsoft both indicated my notebook was ready for upgrade to Windows 10, but when I tried to do the upgrade it failed - repeatedly - with the error message from Microsoft that "we couldn't update the system reserved partition." What to do?

The system reserved partition serves a purpose. If it is deleted, then the OS will not boot back up. In which case you are toast.ON THIS PAGE, it tells what the partition is used for.-The Boot Manager and Boot Configuration Data : When your computer boots, the Windows Boot Manager starts up and reads the boot data from the Boot Configuration Data (BCD) Store. Your computer boots the boot loader off the System Reserved partition, and it boots Windows from your system drive. I advise that you not do what CanhThanh is instructing

[Boot] System reserved partition and SBS 2011 located on 2 different drive preventing hardware upgrade

Hello
After a couple of years enjoying SBS 2011 and playing little with it as it run fluently, I faced a storage issue and wanted to upgrade my SSD from 128 to a bigger driver. Problem, after copying the old SSD to the new one, the server won't boot anymore (error
0xc000000e at launch, even before windows startup).
After digging a bit into the issue, it looks like all is because of a bad installation, 3 years ago. 2 drives were connected back then, the system SSD with 128gb and a data driver with 1tb. During installation, it looks like SBS 2011 created the system reserved
partition 100m on the data drive (d:) and windows on the system drive (c:)
So now I am quite stuck, as if I change the hard drive 128gb, I just face that boot error and I didn't manage to find any suitable solution. I tried a repair function from SBS 2011 install DVD, but it does not recognize any viable OS installed. I tried in
command line to check if the System reserved partition was active with Diskpart and it looks like so... but I suspect that it does not recognize the new drive as legit and won't look for the windows directory in there.
If anyone can help me here, I just can't imagine reinstalling everything :(
Cheers

Hi,
Sorry for my delay. Would you please let me know current situation of this issue?
Based on the description, I’m a little confused with this issue. Would you please let me summarily know how
copy the old SSD to new one? In addition, did you refer to following article and check if can help you.
Use Bootrec.exe in the Windows RE to troubleshoot startup
issues
For error code 0xc000000e, it may indicate no such device,
If any update, please feel free to let me know.
Hope this helps.

Windows 10 could't update the system reserved partition

Installing Windows 10 leads to the following from on the Windows update screen: Windows 10 couldn't be installed We couldn't update the system reserved partition. What now?

This worked despite myself: Didn't enter the right amount of spaces between "/"s, skipped the attrib part by accident, and when I couldn't find the file explorer options moved on the the chkdsk command. Since this was for Windows 7 to 8 figured the later may not be necessary. Failed install with code C1900101 (if memory serves.) Saw folks on other boards with driver issues, I disconnected my external monitor and was able to install. All is well, so thanks.

Restore ASR System Reserved Partition

Hi community.
My ASR Boot environment has been damaged when my colleague inadvertently loaded a windows 7 standard image to my RAID array.
After moving the Windows 7 installation back to the dedicated drive and off my RAID array i configured the Boot store to boot windows 7 with the restore repair option available in the F8
menu.
config included below.
However whenever i try to load the ASR WinRE environment (the same you would otherwise have on your Win 7 instalation disk) i receive the
0xc000000e boot error because the media is inaccessible.
I have fixed this such error befor but only when the System Reserved ASR partition is not present and Windows 7 is the only thing on the drive.
However i cant seem to revive the boot capabilities of the ASR from the repair option in the F8 menu.
Has anyone got any ideas of:
How I can fix my System Reserved ASR boot environment
or
How I can replace the boot environment with a fresh copy.

Hi,
Did you mean the “Automated System Recovery” option, as I know, the ASP backup and recovery option is only
part of XP or Windows Server 2003, while in Windows 7, we have more advance recovery options such as
system point restore, restoring from a regular backup.
See revocery options in Windows 7
