Resolved W7 is able to start only with Repair Disc inserted

When I turned on my laptop after months (without CD), it just gave me a BLSOD.
Then I did startup repair with the repair CD, ran memory diagnostics, but it said 'no problems detected'
After that I restarted my laptop, forgetting to remove my repair CD. Then W7 booted up as usual!

However, when I removed the repair CD while I boot up my laptop today, it stucked at the boot screen for five minutes, then it returned me this error message:

(I know when Windows failed to boot up and the error message is from WINDOWS BOOT MANAGER, the time has come for my old laptop. Thank goodness 90% of my data is backed up)

It's pretty unusual because Windows is supposed to boot from HDD instead of relying on CD. Tried safe mode but no avail.

What should I do?

 

This time I tried to boot from my repair disc again.
However, it took forever to go into command prompt. The machine hanged.

 

10 minutes to boot from CD, then after I selected 'system recovery options', then the system hanged.

 

It took forever to run the long generic test.
I think it's the failing hard drive that causes the problem.
Is it possible to make it as a slave drive for my new laptop? (I will just buy an external case and transfer the remaining 10% of the files to my new laptop)

 

Isn't it similar to this?

 

Okay thanks Evan Omo! Sorry for the late reply because I was dealing with mid-terms last week.
I think I'll put this thread as 'resolved' for a while, because my old laptop is not with me now.
Admin, can you KIV this thread until I got my hands on the laptop? Thanks

 

Thanks Admin.

Finally I got my hands on the laptop! I inserted the repair disc, but it performed system restore instead when I pressed 'System Recovery Options'.
After rebooting, my laptop miraculously works!! But after the next cold boot it shows the same error message again.
I tried to use Seatools for DOS, but don't know why it refused to burn to CD or USB. In the end I used WD Data Lifeguard Diagnostics for DOS (since my HDD is WD), ran the extended test, but no error found, even though after 5 hours of scanning. I tried restarting the PC after that, when it comes to Startup repair, it powers itself down suddenly.

In short words, my laptop refuses to boot normally.
Ruling out failing HDD, what should I do next?

 

Last night I tried the method that you show in post #2. When I attempted to repair BCD at the first time, it doesn't work, because BCD by default is write-protected (since it's system files) and I need to add the following line : "C:\Boot\BCD attrib -s -r -h" in order to continue. Maybe you can add this to your guide. Just my suggestion though.

And another weird phenomenon happened. Windows is installed in C: drive by default, but in command prompt it shows in D: instead. Is it normal?

By the way, after I performed the steps as shown, windows booted up miraculously!! After trying a few times, yes it works!!

I didn't modify any BCD files, MBR and these stuffs months ago. Why BCD files will corrupt after leaving my laptop unused for months? This is not normal right? Is it an indicator that my HDD is failing? Or any other reasons?

 

Okay.
Thanks and that concludes my problem.
Thanks Evan Omo!
