yes, all you have to do is get into safe mode and switch basically this video in reverse.

Hi, no, it's not Legacy necessary, but UEFI is better, just google Legacy vs UEFI

@@firstnamelastname3464 you can try pop os or Fedora 34 beta. I was surprised suddenly installation detected my HDD. Download latest pop os or Fedora 34 and make sure to choose UEFI and GPT while making live usb from Rufus. Wish you good luck ☺️. Because recently released laptop/pc won't support linux initially. It will take some time for driver support. Still ubuntu,mint mint do not detect HDD, of my laptop ,in my case I have installed pop os and it's working fine.

[@1234party]

did u fix it? I got the same problem

[@XYZB0RG]

​ @1234party your computer may not have been built with support for legacy booting. I think it's stupid that modern computers are being built without the choice to legacy boot but that's just the way it is. I've heard rumors that you can mod your computer to support legacy boot but I've never done physical tech modding like that before so I'm not your guy for that unfortunately. if you're trying to run a pre-windows10 OS like I was (in my case, I was trying to run windows 7) then your best option is to use a virtual machine.

Hello there i need your help, I had to install win10 via bootable pendrive but I couldn't do so and I found the solution was to change from RST to AHIC, when I changed I was able to install windows successfully but my pc lagged a lot and my disk 0 was 100% consumed all the time. Then I tried to change from AHIC TO RST but my laptop crashed. Can you tell me anyway of installing windows 10 but keeping RST mode and not AHIC. Please help!

[@mmktut]

Hi, I think your hard drive is damaged. so, first of all, try to fix it: Go to "C" driver (Windows installed drive) ↪ Properties ↪ select "Tools" tab ↪ and Check. if you Windows find Errors let me know the error. also, you can open cmd as admin and type: chkdsk C: /f /r /x this command finds and fix your errors on your drive Then Go to "C" driver (Windows installed drive) ↪ Properties ↪ select the "General" tab and Clean up system files if you find (Previous windows installations) mark it as well it may take a lot of space. If it no helps please let me know, and we try to install Win on RST you can find my Facebook contact in the video description

Hi, there maybe a couple of reasons, first, you may didn't save changes, so please try all steps again and make sure you save changes by f10. is your laptop Lenovo? and also please let me know your BIOS version if the BIOS version is the same as in the tutorial, then you missed up something so try again step by step.

If your next try does not work, then you can also try to disable secure boot, if it is grayed out too, this tutorial helps you to fix it: kzbin.info/www/bejne/fZemiq19a5yNbqM Thanks for watching and please let me know if you find my reply helpful
