Can't Upgrade Windows 7 to 10 because of small Reserved Partition

Win 10 isn't better than Win 7 and you can regret of doing the "upgrade".
Use your Win 7 to build the Factory recover disks.
Once you have the Factory recover disks you can delete the Recovery partition and expand the System partition.

Windows 7 is designed to operate with a system partition of 100MB although this is more than is needed, so it is sometimes reduced As Windows 10 uses the system reserved partition for a lot more tools that Windows 7 did it requires a system partition of 450MB +

From your map I would suggest you use the Dell software to create recovery disks / Thumbdrive if you have not already done so

Next use partition wizard to remove the recovery partition
Upgrade win7 to Win10 and the system partition will be expanded as needed automatically, (using the free space created by deleting the recovery partition) after everything is finished and installed you can if you wish use partition Wizard to Move/Expand the C: drive to fill the free space.

If you decide on a fresh install of Win10 then there is a drive options sub menu during install that allows you to clear all partitions and create those needed automatically, (NOTE THIS OPTION WILL DELETE ALL PERSONAL FILES AND INSTALLED PROGRAMS), which will provide the most stable install, but requires backup and restoration of files and reinstallation of programs

Hi All,
After some time I did a workaround on one computer. I used Recovery CD to install Win7 once again and then upgrade to Win10. That solution works. But i wanted to save all data and profiles so i tried with 3 party solutions. I try one more time with minitool and it start to work. I don't know how because i tried it before! I will confirm it on third laptop!

Hi,
You can also use easy bcd to copy the 100mb system reserved to the C partition and after delete the little bugger completely
Bootmgr - Move to C:\ with EasyBCD - Windows 7 Help Forums

I'd also make a system image before you upgrade so if it fails..... at least you have something to fall back on to start over.

A partition can be extended into contiguous free space.

You would need to shrink C from the right to create that.

It can be done from outside windows, using boot media.

Probably simplest is to make C the active, system partition. Then delete the 30mb part.

Thanks for quick reply @samuria
I cant delete or extend this partition only shrink. The same with third party software EaseUS, AOEMI.
@billmcct
When i choose extend system partition it see only C: partition not this reserved. When i click directly on this partition i can't extend it.
I had a 4-5 laptops in my hands with win 7 and there always was 100MB partition at least.

There is one way that u can do that and that's by reinstalling windows 7 after u hv gone to boot than u should go to costum intallation and format the drive.Sure u should bckup files.Tyen after having clean drive try again intalling windows 10.
