Okies, so today I backed up my files when prompted by the little flag icon, they went on an external HDD. Updated everything. Went back to pc after tea, and when i switch on it can't boot windows. 1.. it asks me to put the cd in, when i do it goes through to the option to upgrade, repair or custom. If i try to custom install it tells me no drives were found. 2It won't let me upgrade either. So i put the disc for the motherboard etc in and ask it to repair it says IDE drive doesn't exist or ALL primary partitions are occupied HELP!!!
