Windows 10: How to remove windows 7 from w10/w7 dual boot? Each OS is on it's own hard drive.

I originally had w7 and then installed w10 in a dual boot setup with each OS being on it's own physical drive. I now want to remove w7 entirely from my system but I'm not sure how to do that. Without the drive that w7 sits on (by disconnecting the sata cable), the w10 drive doesn't register as bootable in the bios. It's like the boot flags are only on the w7 drive and without it I'm bricking my system. Any advice on how I can proceed without bricking my system? It'd be great to finally be rid of having 2 local disks: https://i.imgur.com/SLhX7Vi.png (disk F is the one where w7 sits and without which I cannot boot up at all right now)

W10 corrupts W7 hard drive

W8.1 was working fine as a removable hard drive. W7 installed on a RAID array as multi partitions. Works fine and both OS can be booted and W8.1 reads the RAID array when booting as W8.1

W10 upgrade completed on removable 8.1 drive, but then checked RAID drives for errors and changed them.

W7 on raid no longer boots. After severel hours W7 finally re-installed on RAID array. (data is on other partition so ok.) Tested working all data recovered.

Here's the kicker.

As soon as I boot from W10 it says "reboot required to fix drives" then corrupts the Windows 7 install... Which doesn't need fixed!!

The drive containing W7 OS becomes unreadable although other data partitions on the RAID array are OK.

W7 recovery tries to fix the hard drive then fails.

W10 changed drive letters first attempt, so I thought this an easy fix, but in fact every fresh W7 install is corrupted as soon as I boot from W10.

This is a major problem. Why is W10 changing the drive parameters on a completely seperate fully operational operating system?

 

Is it possible to dual boot to w7 after w10 install w/o removing w10?

Upgrading possible ? Dual boot (XP-32 / W7-64) to (XP-32 / W10-64)

Hi everybody,

I have a dual boot PC with Windows XP (32 bits) and Windows 7 (64 bits), both installed on a 500 Go SSD.

I have a 500 Go HDD for My documents, other data and games. Having two drives on a PC didn't cause any problem for upgrading W7 on another PC
but there was no other OS.

My 2nd PC is declared to be W10 compatible.

The active partition is the one with XP. So the one with W7 is
not active.

My two questions :

• Will the upgrade process be able to upgrade W7 even if it is not the active partition ?
• Will XP and the dual boot persist ?

Any experience with dual boot and W10 upgrading ?
