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.

Hi Debbie!
since your reply shows you have intimate knowledge of the "SYSTEM RESERVED" paritition maybe you can help me with my issue...i used a "clone disk" tool to copy a new install of win7 home/prem to a 128G SSD, and the tool didn't exactly "clone" the disk...it copied the data and created the three partitions RECOVERY, SYSTEM RESERVED, and regular boot/page file primary data partition, but it CHANGED THE SIZE OF THE PARTITIONS!
the SYSTEM RESERVED is supposed to be 100MB, but on my new, WORKING SSD it is only 31MB! ive tried several tools to increase the size of this, but it will only let me shrink not grow the partition...i even unallocated a few gigs thinking i could copy that partition over to a new, bigger partition but so far nothing is working for me...
copying an existing OS install from a HDD to a SDD using a clone tool should be becoming a rather common request, and as i said the clone IS working and the performance of win7 is outta this world!! shouldnt microsoft offer some sort of tool to aid in the process of performing the act?
perhaps one exists already...if it does or you have any ideas how i can increase the size of that partition, i would love to hear about it...
thanks for your time, and have a great day!

can we add this system reserved partition to the partition in which os is installed so that it looks like single partition
Hello saurabh13 ,
There are many advantages to having the "System Reserved" partition. However, Vista and Windows 7 will work fine without it.
You cannot "add" it to another partition, but you can delete it. Before you do that, you would need an install DVD or the "System Repair" CD Windows will make for you. You then mark the "OS Partition" active, boot to the DVD or CD and perform the "Startup Repair" (you may need to repeat the "Startup Repair" as many as three times to complete all the changes necessary). When you are able to boot to your OS successfully, you can delete the "System Reserved" Partition.
You will need a third party utility (not Microsoft) like the free Partition Wizard
http://www.partitionwizard.com/free-partition-manager.html
to extend the OS Partition to the left in order to add the 100MB of empty space to the OS Partition.
There may be unwanted results to your computer depending on how it is set up, so backup everything and proceed with caution!
Cheers!
