Multi Boot Problems
Not sure if this is the correct sub-section but I trust the admins will move it if necessary.
I have an old Dell Optiplex 755 SFF which had installed Windows XP Pro, Windows 7 Pro (64 bits) and Windows 10 Pro (32 bits) used mainly for test purposes.
I haven’t used it for a while but when I started it up this week it won’t boot into XP nor 7 but will into 10 Pro.
All three OS are on separate partitions on an SSD. I have done sfc /scannow and a chkdsk and all report good.
When I boot up I see the BIOS screen (can’t remember the exact name for it) and then I get the choice of which of the 3 OSs to boot to. But with 7 or XP it just gives me a few seconds of their start up screens and then goes back to the BIOS screen.
I have tried using Boot Repair Disk (not sure whether to use 32 or 64 bit versions so used both) from yannubuntu and also Dual boot Repair and Visual BCD Editor from boyans.net but still get the same results.
I booted up with a Windows 7 Pro (64) USB and when I got to “Unable to Start” I tried its Boot Repair menu 3 times but always get “Cant’ Repair-NoRootCause”
Anyone got any ideas?

Just noticed something that may be very relevant.
In Disk Management I see that the Win 10 partition is described as Healthy and Boot, but XP partition is Healthy and Active.
I tried to change Win10 to Active but it reverted back to XP being the active one.
