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.

Thanks anyway,
i wil try a install with an different harddisk.
I'm not trying to delete the 100mb... I want the letter to vanish!!! One of our servers, with valuable software installed, suddently moved the boot disk from C: to D:.
Booting from the installation CD and running DISKPART I can see the two volume letters, however, they can't be deleted. Also, DISKPART and Regedit runs on the mini boot and not on the server. With this condition I can't boot the server. To have a C: drive with just 100mb and nothing else is not helping.
Any advise will be highly appreciated.

After a system failure I started backups to other internal drives that were then disabled. Minimal voltage is still supplied for detection but this still seems better than RAID options. With many reports of external drive failure and recognition problems (probably related to automatic backup with sleep issues) as well as security risks I am establishing secondary backup to another system. Only images would be moderately secure. Unfortunately the transfer rate may be slower than to even a USB external drive. The addition of a new drive seems to be very convenient for migration to a new OS but not compatible with maintaining the current setup with Windows 7. Over ten years ago, secondary drive setup was discouraged but at that time RAID was also in a sad state. Something changed since XP and Vista so I need to know if I need to adapt or if the OS will update.
Yes I put the optical drive on port 0 and SATA boot drive on port 1. The hard drive failure resulted in loss of port 1. I was able to again use port 1 but it is no longer recognized as Disk 0 after significant effort. The system reserved partition space remains on the orginal boot drive, so using the installation disk, that can be restored and the one on the second drive can be deleted. The problem is knowing whether the hard drive, motherboard or OS is primarily at fault since collaboration is involved. I considered BCDEdit at that point but I have other things to do after considerable hardware problems over the last two years.
