So a brief explanation is that i was partitioning my hard drive when it was at 87% my computer completely froze. i let it sit for hours and still nothing so i had to turn off the computer. the next day i tried to pick up from where i last left off but now when i run it off my windows xp disk it says that there is no hard drive. i went into bios and still does not recognize a hard drive. any help is appreciated thank you!
