Yesterday I installed the Avast antivirus software on my windows xp pro machine. After letting it run a complete scan I then uninstalled Norton AV, which required a reboot. When the machine tried to reboot I got the Blue screen with an error message and it did a memory dump. Upon rebooting I got an "error loading O/S" message. I tried using the XP recovery after booting from the cd but got no options and when I let the machine boot from the cd it only sees my physical D drive but not the C drive, it says there is no recognized partition. I created a bootable Acronis disk and booted using that and tried the recover partition utility. when I click on the icon for the c drive it shows: FS: None Partition 0x7(NTFS, HPFS) File system: None I tried automatic recovery and that did not work. When I choos manual, it will not let me select the portion (highlighted in yellow) where my c: partition was/is. The yellow bar has a red and white x on it. The only thing it will let me select is an unallocated 7.8 MB section. Now what do I do?
