I solved the issue by running Dell Restore and recovery app. Thanks for everyone's help.
When I upgraded to Windows 11 on the 5070, I kept the hard drive from my 5050 which has Windows 10 on it. I installed the Windows 10 drive in the 5070 and had both 10 and 11. I used the BIOS to switch between the 2 OS. It worked fine until yesterday when I got into an "automatic repair" loop with Windows 11. I tried some online solutions to fix the problem, but I only made it worse. One of the methods I used involved using bootrec.exe to change some boot settings. When I look at BIOS now, I only see the Windows 10 drive. I can still see the Windows 11 drive in Disk Manager and Device manager. Any thoughts or help on how to get access to Windows 11 drive will be appreciated!
