I was changing the case and PSU of my kid's desktop computer. It was 2015 HP Desktop - Intel Quad core computer. Lots of parts and upgrades being done on it and latest one was GPU(Nvidia 1005 Ti)-so it was due for a change of PSU and case(for better airflow). It has 5 SATA port on - as the new case is not having the 5.25" bay - so DVD drive cannot be used. It had two SSD and one 3.5inch hard drive. I didn't took a picture of how the SSDs and hard drives were connected on this motherboard. Everything is done within few hours but we are getting this error POST BIOS: No boot disk has been detected or the disk has been failed. Tried various combinations to connect the hard drive and SSDs on the motherboard - error not going away. I took out the SSD and found that SSD(500 GB) has Windows, SSD(1TB)- Windows D drive or data only while the 3.5 inch hard drive is Ubuntu Linux. I have no idea when we last time created dual boot - where GRUB or LILO was installed. My son didn't used Ubuntu at all so we can afford to uninstall/delete Ubuntu Linux and install it when needed. I somehow logged into that computer and created Windows recovery media(on USB). Now how i can uninstall Ubuntu and GRUB/LILO so that it's pure Windows computer?
I will instal Ubuntu Linux on that computer, later when the kid develop some interest for Ubutnu linux.
