Sudden fail to boot - possible partition issue? Win7 Ultimate 64bit
Hi all,
First time here. I've been reading through lots of issues and resolutions of failed boots.
I think I have a slightly unusual problem because some items aren't working.
I've disconnected all other drives and just have the primary Win7 (ultimate 64bit) drive and DVD drive connected.
The main bootable drive is a GPT drive (3TB and boots).
Issues started when I did a normal restart after seeing RAM usage was high.
Suddenly no booting into Windows - 0xc0000225 - the boot selection failed because a required device is inaccessible.
The Win7 repair disc I attempted to create from my work PC (also 64bit, but not ultimate edition) didn't work at all.
The Win7 install disc I inserted works - but the system repair options are unavailable because apparently it's a different version (SP1 through years of updates maybe?) I dunno.
Using SHIFT + F10 I get to the console, from where I've been following other posts' guidance on what to do.
If I go to DISKPART, I can find the 3 partitions on my GPT drive
Partition 1 System 100MB
Partition 2 Reserved 128MB
Partition 3 Primary 2794GB
However, after selecting partition 1 I am unable to mark it active because: "The selected disk is not a fixed MBR disk"
If I list Vol, I can see that Vol0 is the Win7 CD, Vol 1 is drive C formatted as NTFS as one would expect, but Volume 2 (Now selected due to selecting the partition 1) is listed as FAT32? This seems weird. (Also has hidden attribute)
Using BootSect I can copy the boot files, only under force. (/nt60 /force /mbr)
But I am informed again it is a non mbr system.
Using Bootrec I can run fixmbr, fixboot and scanos, but when I try RebuildBCD it completes and is then unable to add the record to the boot list because:
"The requested system device cannot be found"
I've run CHKDSK /f on the drive.
I've also done SFC /Scannow - which eventually terminates with the message "there is a system repair pending which requires reboot to complete. Restart Windows and run sfc again."
Is it possible the FAT32 format is incorrect? It appears that the GPT disk is giving issues because of this?
I would really appreciate any help or insight as to what is going on and how to fix it.
(As an aside - I managed to get a USB repair 'disk' working to some degree - but the system repair could not find any entries of a windows installation - which I think points towards a partition issue? I ran the system repair utility form there about 20 times but to no avail - I read somewhere else that the USB could have driver issues and not work properly, and so that's why I've switched to the DVD.)
Thanks in advance for anything that would help - I really appreciate it!
