so my dads computer just...hit the error with unmountable boot volume and i have tried...everything now i found a way to fix it...using the windows xp disk to boot in recovery mode..but we lost that and i have contacted dell and microsoft about this and they cant help because no support obviously...now if i get a new disk off of ebay will i be able to boot in recovery mode..and what if the disk says for distribution with a new gateway pc can i still use it for ..my dads computer and boot in recovery mode and can someone give me a link to windows xp pro disk to buy..because i cant trust myself looking at these disks because i might get scammed.
