I am unable to boot up my ASUS Notebook (X55U). The only Boot devices that are detected in the setup utility are:
UEFI: Atheros Boot Agent
UEFI: Atheros Boot Agent
UEFI: HL-DT-DT DVDRAM GT70N
When I try to boot from a recovery disk I get a message that says:
"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disk and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."
Info: The boot selection failed because a required device is inaccessible."
At another time I got a message that narrowed the problem down to "\EFI\Microsoft\Boot\BCD (Status: 0xc000000d; error while attempting to read the boot configuration."
My hard disk is detected under the "Advanced" tab in the Setup Utility under "SATA Configuration," along with my CDROM drive. My hard disk is listed as [AHCI].
When I try to add a boot option I am given the file boot options of ＜ASUSLog＞, ＜BOOT＞, ＜DisableS3S4＞, ＜EFI＞, ＜SOURCES＞, ＜$RECYCLE.BIN＞, all of which turn up nothing that solves the problem.
I am also left with no option to customize my own boot path.
Under my "Boot" tab I have no access to any other Boot Configuration where I did before. No fast boot option, No enable CMS, etc. Launching EFI Shell turns up nothing even when my recovery disk is in the CD drive.
What I have already tried:
- I have removed the battery from the motherboard to reset it. (This only reset the administrator and user passwords.)
- I have searched with no success to locate a reset pinhole.
- I have removed the battery and booted; I have removed the AC cord and booted.
- I have attempted to repair with both the Windows installation DVD and also a recovery disk, but the computer freezes on the Windows logo.
- I have tried another hard disk which was also detected under SATA but did not show up as a boot option.
I just purchased this laptop in March of this year. Unfortunately, my husband lost the invoice, which effectively voids my warranty even though I registered my damn product online upon purchase. Within the first month I have already had to replace the hard disk at my own expense after it buggered up when I disconnected my laptop from a HDMI cable. After three straight days of working in vain to recover it I am seriously fighting the urge to chuck the thing out a window (resolve growing weaker by each maddening minute). .
Any suggestions as to how I might be able to resolve this issue would be much appreciated...and possibly even prevent a future breakdown.
