My Insider Preview build laptop busted

[davidhk129]

It might be just a coincidence.
Yesterday, build 10547 was installed, today system said " repair is needed and will restart afterwards".
Then it said " unable to repair".
I couldn't do system restore because there was no restore point available. I didn't create one. Forgot.
I then tried Reset....... unable to because file missing.
I then tried system image backup....... file corrupted it said.
I then rebooted and it said " missing operating system".
Now I am really busted !
I then popped in the build 10532 bootable DVD and did a clean install, and at 54% it said corrupt files and aborted.
( P. S. it accepts the generic product key. Surprise !).

So, I inserted my Win 8.1 bootable DVD and clean installed. That worked.
Why did it work while bootable 10532 DVD did not? Damned if I know.
I am now in Win 8.1 and Windows Update is downloading Windows 10.

I wonder if I would try switching Win 10 to Insider Preview again since I already have another laptop running Win 10 Home RTM.

Are you certain that the hard drive is in good shape and free of any bad sectors or other problems?
I can't even begin to guess why one install worked and the other didn't unless there is a problem with the 10532 DVD.

I have to wait till I do a disk check.
I have not done a disk check for at least 2 years.

Win 10 Pro has been reinstalled via Win 8.1 Pro via Windows Update.
It took eternity.

I'll wait for next Insider Preview build before I consider going back to the program.
