Windows 10 Repair Disk

[Alicat58]

My elderly dad has a PC that was custom built to his own specifications about 10 years ago. I am not sure about which version of Windows it was using but it was 32 bit. Since then he has installed a 64 bit system and it was running Windows 10 very well until this week.
When it started up, for some reason it always gave the option of Windows 10 or Windows 7 which was no longer installed. My dad tried to get it to boot it up without the Windows 7 option but now it will not run any programme. He can only get as far as the boot manager or the set up page and no further.
I tried to make a Windows repair disk on a blank DVD but when put into my dad's PC it just came up with disk error and would not run.
Should I have used a blank CD or is there somewhere I have gone wrong? I am not a techie but have heard of data CDs and wonder if this is what I should have made. To be honest, I don't have a fecking clue what to do now. HELP!!

Not being there to try things I'm not expert enough to advise based on the above and not knowing what your father changed; but I'd suggest trying a CD rather than the DVD must beworth a try. A little surprised the PC is able to create one before booting, not that I've ever tried.

Sorry, I created the repair disk on my PC. I will try a CD though. Thanks.

Most likely the Windows Boot-up partition configuration is corrupt.

Try creating either a Windows 10 Installation Boot up DVD or a USB Boot UP Drive as per the following instructions:-

Using the newly created DVD or USB drive, you can then attempt a Windows 10 Reset operation as per the following instructions (See the section "Using installation Media to Restore or Reset your PC" and follow the 'Reset' info)

Just another thought, is your Dad's PC CD Drive capable of reading DVD's and not just CD's?

if it reads CD's only then you will need to create a USB boot-up drive.

Thanks pinkyboyid. I have created a DVD and will try it out when visiting my dad later today. :D
