Windows 7 can't see other OS

[vec0n]

Hello! I can’t find solution for my problems and in need for Your help.

I have Win7 and Win10 installed on different SSDs. From my mostly used OS(Win7) i can’t see other OS. Booting into Win10 and switching back to Win7 starts 10min+ CHKDSK which is annoying. The SSDs are new. So the question is - how to let Win7 see that there’s also Win10?

I have Win7 and Win10 installed on different SSDs.

Dual boot has to be on the same drive and Windows 10 installed after Windows 7 was.

The BIOS can only boot from one drive and that drive will be the one that you prioritise in the BIOS, Windows by default allocates this drive the letter C:.

That makes sense. Any idea why switching between SSDs windows asks for CHKDSK?

Is the disk check happening from a cold boot as in if the PC is off over night does the disk check happen if you boot straight into Windows 7 the next day.

Yes, next day in the morning I’m booting in Win7 and CHKDSK starts.

Nothing to do with switching between drives then so check the health of the Windows 7 drive first.

Disk seems fine, but maybe I don’t see something.

The health of the Kingston with W7 on it looks fine which suggests that it is a problem with W7 itself.

Take the W10 drive offline and then run the Windows AIO repair tool, see the below;

Download then run the Windows All in One Repair tool from here, disregard the malware guidance but follow the other steps to the letter and in particular ensuring that you first create a new restore point and perform a proper Windows clean boot before running the repair, details for the clean boot here.
