That could corrupt hard drive contents so decide which mode you want, save your files to your backups and restore the machine with either the onboard restore or restore media.
If restore efforts fail, your laptop needs repairs. And I've never seen a Windows Update cause all this. I have seen a HD get very corrupted by changing the mode.
You bring up a good point. Is it time to lock out or remove BIOS options like this?
ASUS G60VX Windows 7
I am the most desperate I've ever been.
1. Windows 7 Recovery Disc using ASUS Preload Wizard attempts to partition suffers error 1117: "ERROR: C:\ASUS.SM. [_wim_create_file:(seq. 10) -> Fail to read WIM header] [err= 1117]
2. Attempts to boot normally gives: "Missing operating system" on a black screen.
3. There is no way to access command prompt.
After a windows update, my normal desktop began to freeze and I had to force shutdown my laptop by holding the power button. After I started the laptop up, Windows could not boot normally. Trying to boot with safe mode, the driver loading messages froze at CLASSPNP.sys. After using the BIOS to change the IDE to "Compatibility" mode, the continuous loop of the Start-up Repair Utility plagued my system in every single boot option (spamming F8) with no repair in sight. So I decided to use the ASUS Win7 recovery CD to return my laptop to manufactured condition. This also failed giving me either the error 1117 message or the "cannot set temp path to work in."
I've changed the boot device priority to CD/DVD in order to access the Recovery CD that gives me the 1117 error.
All I want to do is return my laptop to manufactured condition and get out of this chaotic loop.
