Windows 7: C: Reserved?

C: Reserved?

Hey guys, My C has a partition with a system reserved. This is normal, correct?

system reserved has usually been 100mb I belive everytime i have noticed it over the years with a certain amount of data on it. Recently I have loaded a saved backup image as my pc shit itself, and now i have noticed my system reserved is much larger - 59.32 gb with 59.23 gb of free space.

Can I use disk managment in windows 7 to reduce this partition in size without affecting the data needed on my c drive?

the reason is i only have a small 320gb ssd that is near capacity and i would like to free up the 60gb in the system reserved to install some software.

What has happened to cause the change in size of the system reserved?
what is the system reserved?
can i reduce it/ delete it to the regular 100mb allocation?

Please help.

Thanks,

jp

Yep, somethin`s way wrong with that. Can you post a full shot of disk management.
Make yourself a system repair disc if you do not have a Windows 7 install disc b4 attempting anything.

Yes, it is normal for some hard drives to include a system reserved partition. It depends on how the operating system was originally installed as to whether there will be a system reserved partition. This 100MB partition is a system partition and contains boot files. The general "rule" is as follows"
  • If you want to have the 100 MB System Reserved partition in addition to the Windows 7 C: partition on a HDD or SSD after installation, then you would need to make sure that all partitions on the drive have been deleted until it is only unallocated space. Next, select the unallocated drive to install Windows 7 on. If there are no partitions on the disk, you will get the 100 MB System Reserved.
  • If you do not want to have the 100 MB System Reserved partition partition and only the Windows 7 C: partition on a HDD or SSD after installation, then select a formatted partition or drive to install Windows 7 on. If there are any partitions on the disk, you won't get the 100 MB System Reserved.
Source (see Note after Step 8)

Since the partition contains boot files I would be very careful about altering the partition size. I don't know the mechanics of how shrinking a partition affects the data on that partition - if the data gets moved or if it just gets deleted.

This tutorial shows how to delete the 100 MB System Reserved partition and do a repair so Windows 7 will still be able to boot. I don't know if the partition will remain as unallocated space or not. But if it does, a free tool called Partition Wizard should be able to extend the C: partition using that unallocated space.

system reserved partition weird-out!

Thanks for the replies.

I use acronis 2013, and I have a complete image of my c: drive, but also with it in the image I have selected the system reserved partition as it suggests to include it with the backup.

So then, if i have to use this backup if something goes wrong, wont it just load the current partition and the 60gb system reserved again anyway?

Will an Acronis boot disk work fine, or should i just do a win7 one?

I have never done this thing before but I have recently had alot of dramas with a c: drive change that caused me much stress, so im a bit reluctant to try anything without someones guidance that has successfull reduced the size in disk management...

Any other ideas?

Here is a screenshot to check out.

Thanks!

Just took another look at your larger view of Disk Management. Don't know how it happened but it's showing Disk 0 as Audio E: instead of the much more common and usual C: drive/partition.

If you need to use the Acronis image then yes, it will restore that 60GB system reserved partition. Will the image work? It should. But the only way to know for sure is to try it. Have you ever used this Acronis to do a system restore?

Should you also do a Windows 7 system image and create the Windows 7 system repair disk? It certainly won't do any harm to have another backup available just in case the Acronis doesn't work.

If it was my computer, I would use the tutorial on how to delete the 100 MB System Reserved partition, and then do the necessary repair steps to get Windows 7 to boot again. And then I would reclaim that freed up space for the C: partition. But that's just me.

Has anyone used the SHRINK VOLUME option when you right click in disk management? I might try this first. I have backed up everything and done an image in acronis. And created a boot disk in acronis and win7.

Before I do it, I would like to hear if anyone has shrink volumed before though.

Appreciate all your help,

jp
