Problem with installing W10

Sredna · 31 Aug 2015

Is the conclusion still that I have to do a complete reinstall, or would it be possible to repair or resize the partition?

What I would do is install MiniTool Partition Wizard for free. Shrink your large C: drive partition by 250 mb, making 250 mb of free space next to the system reserved partition (so you probably want the 250 mb free space out of the beginning of the big C: drive partition). Then expand the system reserved partition by 250mb - making it 350mb in size. There is no need for boot disks or USB flash drives for that, Partition Wizard will install right in Windows and will do it's own reboot to shrink the C: drive partition.

Then do your upgrade to Windows 10 and after it is activated you can do a clean install if you want to.

@NavyLCDR - that did the trick. I manged to install W10 after resizing the 100MB partition to 350MB.

thanks for your help :)

Just to add to the confusion, I upgraded a Windows 7 Pro X64 system to Windows 10 Pro X64 today with no problems.
It had only two partitions on the hard drive, a 100MB System Reserved and a 239GB OS partition.

The 100MB was marked as System, the OS was marked as Active.

Don't know what that means or why it worked but thought someone would like to know.
