Is there a possibility to install windows 7 (clean install) without making a extra (hidden) partition "system reserved" from 100mb?

or how can I delete this partition after install ?

Why is it for?

I have the meaning that this slows down my hard drive a little ? 

thanks

Hi Johan G,

Thanks for posting to Getting Ready for Windows 7 .

The 100MB partition is a system partition and contains boot files. Disk Manager will not allow you to remove this partition because removing this partition could cause the system to not boot.

Thanks for posting your question to Getting Ready for Winodws 7 community group.

    Sorry I was not clear. I am most happy to "stick with you" if you wish, and I understand if you prefer to have someone local do it for you.

    What you had before your first attempt to relocate the "System Reserved" partition at the front of your hard drive was 101MB of "unallocated space" or empty space. The "Logical Drive" you created in that empty space must go ... it must be deleted. That is what I meant by "delete what you created in the 101MB space".

    Part of the communication difficulty between you and I is that the Windows Disk Management Utility is limited in what it can do. I checked and you are correct, it does not offer a choice of "Primary" or "Logical" when creating a partition. But we can get around this by deleting the D partition before creating the 100MB "System Reserved" boot partition. Also, as you found out, the files in the "System Reserved" partition are protected files, you need to give yourself permission to copy these files to another location, which you did successfully.

    If you want to try again to setup the "System Reserved" partition again, I will try to create step-by-step instructions that do not leave anything out?

    1. Delete D:
    2. Delete Z: (the 99MB "Logical Drive")
    3. Create a new "Simple volume" from the 101MB "Unallocated space" at the front of the drive and give it the letter Z. (I understand the "Logical Drive" was only 99MB. When you create the "Primary" partition in the 101MB unallocated space, it should be exactly 100MB. Please try and see.)
    4. Give the old 99MB "System Reserved" partition a temporary letter like S?
    5. Copy one folder and two files from S: to Z:

         Boot

         bootmgr

         BOOTSECT.BAK

    1. Remove the drive letter S from the old "System Reserved" partition
    2. Remove the drive letter Z from the new "System Reserved" partition
    3. Mark the new "System Reserved" boot partition (the one at the front of the hard drive) "Active"

    Reboot the computer. If Windows 7 does NOT start, boot to the 7 DVD like in the Seven Forums Tutorials and do the "Startup Repair" and reboot until Windows 7 starts.

    If Windows 7 DOES start, you can delete the old "System Reserved" partition. You can "Extend" the C partition. You can create a new D partition in the space that is left over.

    I hope these directions are now clear enough for you. You have done this successfully with the exception of creating the "Logical" partition instead of a "Primary" one, so you should be able to do it again.

    Cheers!

    Robert

    iseeuu--SUCCESS!!

    Using your detailed instructions, I did most of what you said.  Using Win7 Disk Management, two things did not go as expected.  The old Z: (space at far left) would become no greater than 99MB and was again made into a Logical drive when I created a new Simple Volume from the now Unallocated Space.  This even though I had FIRST Deleted D: .

    So I became fearless and used Partition Wizard.  It could not change the size of the new Z: but it could make it into a Primary partition.  99MB seems an acceptable size for things to work.

    I went though all the other steps, still using Win7 Disk Management, and it would seem successfully.  The new System Reserved is at the far left, the old one is gone and I can reboot.  It seems Disk Management cannot increase the size of C: or D: (by taking space from D: or C: respectively)--only Shrink in each case-- but Partition Wizard seems willing to do so (starting from D:), though I did not proceed past setting it up since I did not want to risk messing the data on C:.

    SO MUCH THANKS TO YOU for all the help and taking the time to stick with me. 

    P.S.  A subsequent reboot did require using the Win7 CD.  But since then all is OK.

    Excellent! Well done.

    All partition utilities require you to shrink one partition and then extend the next partition into the empty space. They will not take space from one partition and give it to another partition (at least not yet!). If you delete D again, you will see that you can extend C into the empty space, then make an new D out of the space left over.

    To shrink D so that you can make C bigger, you will have to use Partition Wizard, Windows will not do what you want.

    Cheers!
