Then you can use software such as BOOTICE to write an Windows NT 6.x MBR without needing a Windows DVD.

Ok I will try BOOTLICE.

I tried startup repair a few times and it didn't do anything. Then I tried Easy BCD and I couldn't boot anything.

EasyBCD (and bcdedit) can't help here. Although both are closely connected, it's not about the boot manager but the boot sector, either MBR or partition boot sector. That's why I wrote about bootsect.exe and bootrec.exe in one of my previous posts.

BOOTICE is able to edit the MBR.

Ok this is strange, my current MBR appears to Windows NT 5.x, even though I'm on Win 7.

Should I proceed and write a Windows NT 6.x MBR?

But you're currently using GRUB to boot your computer?

Are you looking at the correct disk in BOOTICE?

Sorry Dalai I was not looking at the correct disk.

I have installed the Windows NT 6.x MBR successfully and it seems to have fixed the missing symbol table error I was getting on boot.

Currently after BIOS says "verifying DMI pool data", GRUB loads, then I can select windows partition, then BCD loads. Does this mean I need to change BCD as default loader instead of GRUB?

Mmh, that is strange. Rewriting the MBR should have killed GRUB completely, making BCD come first. However, I see in your screenshot that your Linux partition is the active one which means that the MBR boots that partition, not the Windows one. The fact that your Windows partition is not the active one may even explain why the (automatic) startup repair didn't fix anything previously.

There are probably multiple steps necessary to be able to get BCD to boot first, and there are many things that could go wrong. I haven't dealt with such a partition table before (I always create only one small active primary boot partition, the rest are logical partitions, including all OS partitions). It wouldn't hurt to try the startup repair again. Maybe someone has a better idea how to solve this in an easy way.

Ok, I could try it again.

I did find this too:

Could give this a try? Would it help my situation?

EDIT:Also what if I use BOOTICE to change the active partition to the windows partition? That way MBR may load BCD first?
