What is this "system" partition?

post #1 of 5
Thread Starter 
I formatted my 1TB HDD then installed an SSD and put windows on there. Now there is a partition (on my hdd i think) called system. What is this and can i get rid of it?



Also, since the SSD install I hear something in my PC power down for a bit, then hear the POST beep and something powers up again. When this occurs, my system stays completely stable, i've checked temps and voltages and it doesnt affect anything, but i don't know what it is.

Big Edit: just follow "Sean Webster's post.

But Note: When installing Win7, You can make it not create the 100MB partion by doing this =

Boot from Windows XP or Vista Disc
Setup Windows Until You Get To The Partion Window, Then under advanced settings Use "Delete" Note: if the hard drive has seperate partions on it "delete" them all, & then click "New" for the "unallocated partion" then Exit the installer,
as the computer restarts insert the Windows 7 disc & install Windows 7 as usual.

(?& hope it wont make the OS unstable,) But i dont think it will.
I'm not sure why it's there either, as usally Win7 will create a 100MB partion that's not usally visible (In Computer).
It contains bootable files to boot your computer in recovery mode, so that it can store recovery options & other information away from the (C:) partition so that malicious parties, or un-knowledgeable users won't destroy the boot partition.
But i believe you could just use the Win 7 Disc for that if needed.

Too bad if he does that his system will most likely not boot if it is from the current install.

What is the system reserve?
Quote:
On a fresh (custom) installation of Windows 7, where Windows 7 is installed onto a new hard disk with unallocated disk space (no partition or volume been defined yet), or when user attempts to create a new partition out of empty drive, the Windows 7 installer will create an additional partition with the size of 100MB, and mark as System Reserved.

The 100MB volume is labeled as System Reserved with NTFS file system, and System, Active, Primary partition attribute with no drive letter in Disk Management. The 100MB system partition is used primarily as BitLocker partition for BitLocker encryption. Additionally, it also holds the Windows Recovery Environment (WinRE) and boot files with boot manager for booting up the computer for troubleshooting when there is no Windows 7 installation DVD disc on hand.

The Windows 7 created 100MB partition is not the main boot partition or boot drive, but serve only as a backup.

Simply go to disk management and right click the partition and remove the drive letter to not see it under your computer any more.

To remove the system reserve partition and not have issue do this:

Remove system reserve partition: http://www.sevenforums.com/tutorials/71363-system-reserved-partition-delete.html

MY GUIDE:
  1. Boot from your installation or repair disc.
  2. When you get to the language screen, press Shift+F10.
  3. Type diskpart, Enter
  4. Type list disk, Enter after diskpart is loaded
  5. Type select disk X (where X is your drive with the System reserve partition on it), Enter
  6. Type list partition, Enter
  7. Type select partition X (where X is your System reserve partition), Enter
  8. Type delete partition override, Enter
  9. Type list disk, Enter
  10. Type select disk X (where X is your OS drive), Enter
  11. Type list partition, Enter
  12. Type select partition X (where X is your OS partition), Enter
  13. Type active, Enter
  14. Close the command prompt

We have deleted the partition, and Windows will be unable to boot at this point. Now it is time to write a new boot loader and BCD to the Windows partition.

Now shut down, unplug any secondary drives, boot up and run start up repair up to 3 times.

If startup repair does not work follow this: (link)

In CMD type:
  1. bcdedit /export C:\BCD_Backup, Enter
  2. c:, Enter
  3. cd boot, Enter
  4. attrib bcd -s -h -r, Enter
  5. ren c:\boot\bcd bcd.old, Enter
  6. bootrec /RebuildBcd, Enter
