Hi guys
This is what happend
I forgot my password (win 7 64 bit) and tried to bypass it by using konboot but since i have an asus motherboard, it boots the boot manager first and not the hdd directly, so i booted from a win 10 disc and deleted primary partition of 100mb, i thought that partition is waste, actually i dnt remember why i deleted it :eek:
When i restarted my pc, it wont boot, if i boot directly from hdd, it would say insert a boot disk and press any key!!
dont know what to doo :(
dnt have my win 7 64bit cd with me right now
I only have win 8.1 and win 10 and (win 7 32bit) cds

You deleted the 100MB "System Reserved" active boot partition which is kept separate from the main Windows partition on some Win7 installations (it depends on how the drive is partitioned prior to the OS install).

I think you can only restore that partition by re-installing Windows.

you put the windows instillation disc of your OS into the computer, Afterwards start it up, boot it from the disk(Can boot from the bios if need be), ONce booted from the disk click install, on the next screen bottom right click repair, now you need to use command prompt.

in command prompt type
/diskpart
/list disk // select from your disks the correct drive
/select x // "x" being the disk you need to replace the boot. often 0/1/2
/list part //this will list the partitions.
/select part x // "x" being the partition that was originally the boot, and is now empty
/active

close the command prompt.

Reopen the command prompt
type
sfc /scannow //will scan and fix corrupted/missing system files(including boot files) on the boot drive, which was assigned by the { /active command in diskpart} //This will also take an extremely long time to verify all of your files and replace missing/corrupted files/folders.

your computer should have no problem booting now, you should still have anything else you had on your drive other then whats on your boot. it will all be fresh.

It's an interesting "fix" you've detailed but tell me...if the user has the Windows 7 OS installation DVD (as your instructions call for), could he/she not simply run a Startup Repair directly from the installation DVD?
I note the OP states he/she doesn't have his Win 7 installation disk "right now", but perhaps it's become available in the meantime.

Startup repair differs from sfc scan, it looks for issues in the boot, it may fix it but the best way to be to have a fresh boot.
