I'm having a tough time with my PC after trying to make it compatible with Windows 11. I managed to enable secure boot, but then I ran into issues converting my disk from MBR to GPT. I tried to set my C drive as 'active' to bypass a lock on it, but that messed things up and I lost access to my games. Now, my computer won't boot at all, showing a flickering white line on a black screen. I can still reach the BIOS, but I've noticed my SSD is in a 'frozen' state. I've attempted resetting it by removing and reinserting the CMOS battery, but nothing has changed. I'm really struggling here, especially since I use my PC for playing guitar. Any insights would be greatly appreciated!

From what you described, it sounds like the partitioning has indeed altered your system's boot path. Try to access the BIOS and change the boot order so it prioritizes the USB drive with your Windows installer. Once booted from the USB, navigate to Windows repair options which might help recover your system.
Before making any changes to your system's BIOS or disk settings, always ensure that your data is backed up to prevent loss. In terms of your current situation, if you're still on Windows 10 and the partitioning has gone awry, I recommend using the command `mbr2gpt /validate /allowfullos`, followed by `mbr2gpt /convert /allowfullos` if the validation is successful. But since your system is inoperable, you may need to create Windows installation media on a flash drive. You can follow the guide at Microsoft’s support site for this. After booting from the flash drive, look for the Windows repair options.
Thanks for the advice! I think I can get the flash drive set up since I can only access the BIOS right now.

I’ll definitely give that a shot! Fingers crossed it helps.
