Loading Operating System error Windows 7

Unable to boot Windows 7, Last thing i want to hear from my kids is ... Dad.. can you replace this junk PC as it is not booting?

Well, it has 3.5 GHz processor, 8GB RAM, 2TB HDD and 20" LED screen and Gigabyte hi-end USB3 Mother board .. blah blah...

"Loading Operating System" and a Cursor blinks at a Black screen.

I tried the System Repair disk which i created (164 MB) and did the Repair for startup problems and also tried System resore and the complete system Image restore... Guess what, as expected nothing helped.

Then i turned to Internet search and found lots and lots of info which did not help, found the Bootrec command, many of them used just one command and it did not help them
I did something different (shown below) and helped in resolving the issue

1) Booted using the 'System repair' disk

2) Clicked on the last option to choose the 'Command prompt'

3) Typed in the following commands one after the other

          Bootrec /RebuildBCD    and hit Enter key

          Bootrec /FixBoot           and hit Enter key

and then

4) Rebboted the PC

Issue resolved
