|I came across the post of December, 2011 now (July, 2013) because I faced a similar problem in a Asus board No.A8V.VM and I think I know that the problem arose after a virus attack therefore I want others to know about it. |
The above mentioned board was running windows XP and a new video card required net.Framework 2 or above to function which was downloaded from Internet and loaded But a virus came along with the Net. framework file and made some changes to memory, even though Deep Freeze was installed but only drive 'C' was frozen, and after that on reboot the screen showed somthing like "no bootable disk found insert a bootable disk and press any key"
There was no problem with the hard drive, cables, power supply or any other hardware fault.
The hard drive had to be 'low level formatted' to remove the virus from hard drive. The virus it seems settled in the Ram chips and caused all sort of problems on subsequent attempts to load an OS (windows XP).
This post is just for information although I am not a computr expert but I think I have discovered the the cause of HDD not being recognised.
