System Reserved Partition

Hello,

I intall W7 RTM on 2 computers. On the first the installation process is normal ... it intalls like Vista.

But, at the secound computer the installation process have created a new partition, the name is System Reserved and the size is 100MB.

Why in the first PC the System Reserved partition wasn't created?

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.

This partiton is, or contains, the "Trusted Platform Module Security Device" on those boards that don't have one of the two chips. I'm guessing and guessing is not allowed.

If you create the partitions during installation it will create that system partition. If you create the partitions from another OS it will not.

That's what I noticed during my 892 build installations.

7 will create a 100 mb System, Active partition during installation if there is not already an active partition present.

If there is an already an Active partition, it will use that as the System partition - presumably in case you already have an o/s installed.

Hello aub7, welcome to Seven Forums!



Before we make any specific recommendations will you please post a snip/screen-shot of the entire disk management drive map with a full description as to which drive/partition is which, so we can see what you have going on as there may be a fairly simple way to resolve the situation.

In the Windows start menu right click computer and click manage, in the left pane of the "Computer Management" window that opens click disk management and post a snip of that.

hello bare, thanks for responding here I left a screenshot of my partitions, the last three partitions are partitions of ubuntu.
Well want to know how I can reinstall the boot, because now I had a problem making a backup of the system and it gave me the error 0x81000033 after some research it appears that the problem was that the partition of 100mb lacked space for a temporary file using the backup windows, giving the solution was to delete the USN journal file system recovery, but not work for me, then I realized it was because of windows xp, surely, as installed in a extended partition, but used as partition C: to boot the system recovery partition so that Windows XP creates some files to booting in system recovery including a pagefile.sys that weighs 40 mb, I deleted that file and then I could make the backup

So I think it would be very useful to know to format that partition and re-create the files in case that is filled with garbage.

thanks.

There are two approaches to take to this problem:

1) Enlarge the 100mb System Reserved partition using Partition Wizard to Resize C taking about 200mb from its left, then Resize SysReserved into the freed space. This may be all that is required, and will save you having to Repair Win7 and possibly XP from boot to write the boot files into the WIn7 partition.

2) delete the 100mb Sys Reserved partition, using PW to recover its space into Win7 and mark Win7 Active, then run Startup Repair up to 3 separate times from booted Win7 DVD Repair console to recover the System MBR into Win7 partition. You can then use EasyBCD 2.0 from Win7 to add XP to Dual Boot: accept offered boot files, autocompletes, Save, Restart.

1st I can not give more space to the reserved system partition, because, I have installed after W7, then would have to remove space to the installation of W7, to give system reserved in my case is very complicated because you see I have the disk full of partitions and therefore would have to modify all.

2nd something I like about W7 is that the boot files are separated in their own install partition, something approaching a little to linux and I find most useful in case of any problem of starting just reinstall that partition would suffice. So such as I have a backup of that partition if the boot fails me, then I just simply restore that partition and not all windows7

So I think that is more useful to know how to reinstall that partition, in case you want to uninstall Windows XP and boot cleaning needless files
