I have an external USB 2.0 hard drive partitioned as two drives (X and Y). On most boots it doesn't appear in file manager in Windows, so no X or Y. Other times it will recognise only Y. If i unplug the drive when Windows has booted and plug it back in it recognises both partitions and works fine.

Any ideas how I can get Windows to recognise both partitions on every boot so i can leave it permanently connected?

May not address your problems...but all USB devices connected at boot should be recognized...I would delete all USB controllers in Device Manager and reboot the system.  If that did not resolve it...I'd take a closer look at the USB drive/connection involved.

not true!

 

if legacy usb mode is disabled in bios then it won't boot from the cd/dvd drive.

and you also need to verify that the drive is selected in the boot devices.

 

all my computers have the boot order with the cd/dvd as first boot device

then hard drive second and so on.

Well...I did not interpret the first post...to indicate that booting the external drive...is an issue.  Reference to Drives X/Y...would not involve booting into Windows.
