|xp pro originally installed then vista, the latter installed on X: with Ram on B:|
Hard disks C: and D: not showing in bios although they worked fine before.
How do I get rid of X: and B: so that I can do a fresh install?
Tried all ways with Hirens and various other repair disks but nothing works. Get message disks read only can't, format.
Can they be unmounted and how is this done, would this work and allow me to format?
