Should be. Glad you mentioned the image backup. You have a usable rescue disk/usb created by the backup software? If it goes wrong, just boot from the rescue disk/usb and restore the old image. I don't think it affects the MBR and System Reserved partition.
This is the way I understand it...the MBR and BCD refer to partitions by physical disk and partition IDs not by drive letters. It is not until the operating system loads that drive letters get assigned. Thus you can change or delete the non-running operating system's drive letter without affecting booting.
The drive letter gets assigned by the operating system after it boots, so the old image will revert back to the drive letters assigned when the image was made but I don't think the MBR or BCD are changed when the drive letters are changed.
Of course it can, Backup & Restore, however, my point for the moment, is why W 10 sees all partitions, which means they're mounted, is it by design or a limitation, and also if just removing the drive letter for W7, while on W 10 would be a correct approach... and do the job without side-effects.
I tried 2 times the installation, same results, so, for some reason, W 10 installation setup does this, for dual boot configs...
B/R,
Does it really matter if Windows 10 sees the Windows 7 partition or not? If it isn't assigned a drive letter it won't show up in explorer or anywhere else other than in Disk Management and you won't be able to read or write to it in normal operations.
It's a Windows thing. Windows likes to reside on the C drive. I have a dual 7 and 8.1 set up. When I boot to 7 on the C drive 8.1 is on the D drive. When I boot to 8, it is on the C drive and 7 is on the D drive. Both reside on the physical drive 0
OK, I used Computer Management under W 10 and removed drive letter D: (W7 partition).
Now, when booting to whatever OS the drive letter of the other OS does not appear in My Computer. :)
No side-effects.....so far.
Will report back in a few days.
Thank you all for your time.
