Hi, i'm trying to format my dads Acer computer that is getting rather old and clogged up with crap and virus's. I've formatted many a computer and re-installed Windows before so i know what i'm doing. When i put in the Windows disc and boot from it, it loads up like normal then i hit enter to continue and f8 to agree. Now, when it it gets to the part where it shows your HDD's and you do the formatting and stuff it just says "Unkown Disc" then underneath it says (There is no disk in this drive.), 4 times over while there is only 1 HDD in the computer. If you hit D to delete the partition or enter to continue the screen goes black and then a BSoD saying a problem has been detected and windows has been shut down to prevent damage to your computer; Technical info: ***STOP: 0x0000008E (0xc0000005, 0xF7640CAD, 0xF721E7E4, 0x00000000) *** setupdd.sys - Address F7640CAD base at F7614000, datestamp 41107c8f Now i'm not really sure what to do at all, and the only thing i can think of is that it doesn't detect the HDD's for some reason, maybe something Acer does to there computers so you have to send it to them to get it formatted or something so they can make more $ but i dunno, any help would be greatly appreciated, Thanks.
