Windows 8.1 boot error
2014-04
I tried to install linux on a second partition of my hardrive, and now I can no longer boot into either system.
The error I get when booting is:
The Boot Configuration for your PC is missing or contains errors.
File: \EFI\MICROSOFT\BOOT\BCD
Error code: 0xc000000f
I have tried automatic repair, but that says it cannot fix the problem.
When i try to refresh PC, it says windows drive is locked
bootrec /fixmbr
completes "successfully"
bootrec /fixboot
completes "successfully"
bootrec /rebuildbcd
finds my OS on "D:\Windows" and when I hit Y to add to boot list, it returns "the requested device cannot be found"
I have run chkdsk on D and C, both say they have fixed problems.
Diskpart list vol shows all volumes as "healthy" although there is nothing in "Info" field
I have an ASUS N53JQ with Windows 7 x64.
My problem started when I used the recovery DVDs from my laptop. Put it in, run the set-up and went to 95%, after that it went to 0% and then to 5%. I got an error code 1029 and could not finish installation. Tried that couple of times and same thing happens every time.
I formatted and deleted and created and formatted and deleted the partition where Windows was on. Tried other Windows 7 installation CDs. 3 in total. Nothing worked. I get a BOOTMGR error when I start the computer, I can't enter F9 recovery partition and F8.
In my BIOS everything is ok. So I tried the repair options from the Windows 7 CDs. Didn't work. I tried:
- Repair your computer
- System repair. Shows no errors.
In the command screen I tried:
bootrec /rebuildbcd
bootrec.exe /rebuildbcd
bcdedit /export C:\BCD_Backup
ren c:\boot\bcd bcd.old
bootrec /rebuildbcd
bootrec.exe /fixmbr
bootrec.exe /fixboot
Nothing worked.
I restarted with CD again, and hit shift + F10
so the command prompt would show up and went to *diskpart > list disk > select disk number > list partition > select partition number > active*, so that partition would become active.
- Partition 1 like 20GB (recovery partition) Primary
- Partition 0 like 160 GB (don't know what it is) ?
- Partition 2 Like 400GB (looks like partition 3, i only have 500 GB total so it has to be the same as partition 3?) Primary
- Partition 3 Like 400GB Logical
The results were:
- Partition 1 could be active
- Partition 2 could be active
- Partition 0 and 3 not.
I read that if a partition is active it will start up first. Did not work for me.
Can someone help me with how to get into F9 Hidden recovery partition while starting up and recovery this machine?
I read somewhere that there were more people with same problem, they had the hidden recovery partition but could not enter it. Saw that some could enter by making that partition active etc. But that didn't work for me. Something about bootloader etc.
I don't want to send it for repair to ASUS because last time I send my last laptop, they shipped it back with a broken frame and defect on my CD player. They say to me they didn't do it, well, I didn't do it either!
Oh and by the way, I can't use an XP CD because I get a BSoD when I use it. Tried 5 different XP CDs, 3 Windows 7 CDs, 1 Vista CD and the Recovery DVDs I made with AI recovery from ASUS.
When the installation disc fails, it's usually:
- Bad install disc - probably not in this case, since different media fails, too.
- Bad hard drive - sometimes this shows when install fails at the same point every time. Easy to verify with a bootable drive scan CD or USB stick
- Bad RAM - can be tough to remove a stick in a laptop to test, but again, bootable media with a RAM checker will answer this for you.
There are lots of threads here to help with testing those bits. http://superuser.com/search?q=test+ram+bootable should get you started.
