100 MB Partition

I have read on here about the 100 MB partition for the MBR. I don't have one. Things seem fine. What is the partition for and do I need to worry about it? Thanks

Hello.



If you did have a desire to create it for whatever reason (I'm not suggesting you do) here is a very reliable method out-lined in this tutorial at the link below; the second tutorial is also an excellent option, though I still have some work to finish that one to an acceptable out-come for XP.

System Reserved : Create for Dual Boot

System Reserved : Create Using Disk Management



This second tutorial is now complete.

Thanks guys for your help. I am a little paranoid these days. I feel like anything could go wrong since a few days ago my water pipe broke in the front yard.

That's the hard way to water-cool the PC isn't it?

If you can spare the 100mb then I'd install to wiped HD (which is a cleaner slate anyway) to get the SysReserved partition - if for no other reason than that it places the Repair My Computer (WinRe) console on the F8 Advanced boot Tools menu. You can repair your laptop in a coffee shop or while traveling without having to have the disk.

WinRe options: System Recovery Options

Here's some other info on the SysResv I wrote for one of the other tutorials but I didn't use it after all.

   Note

• It adds a link to the WinRe (Windows Recovery Environment) that is seen when the advanced boot options are accessed through the use of the F8 hot-key during system startup that can be used to recover from startup errors if a Windows installation / recovery disk is not available for use.
• The partition is suggested for use with Windows Backup and Restore to function correctly, we're now seeing issues if not enough space is available for WB & R to use and creating a larger (than the default 100MB) SysResv partition may solve these issues.
• It is used by Windows 7 BitLocker to store encryption information and will be created by the BitLocker program if it does not exist.
• It creates a single location for the Windows BCD store that the system boot files are kept in, in a dual / multi boot situation and makes removing one of the installed Windows Operating Systems (OS) in a dual/multi boot very easy to accomplish if the need arises.

If I was going to go to all the trouble of a clean install to get the "System Reserved" partition I'd use the method out-lined in Step Two #3 of this tutorial to make it 200MB instead to lessen the chances of it being too small like the issues THIS guy was having when he wanted to add a second OS for a dual boot setup.

We're starting to see a lot of these similar issues with the default SysResv being too small; not to mention the uses listed in the Note in my post above.
