Removed drives during running server ubuntu server 22.04.3 Dell PowerEdge r730xd

Hi I bought a renewed Dell poweredge r730xd from Amazon and he worked fine I used Ubuntu server 22.04.3 but today I wanted to check because I had 3 drives installed but 1 wasn’t in usage so I thought to remove that one but wasn’t sure which one it was and I did that during running server and Ubuntu showed error after I removed every one I know I did something stupid so I shutdown the server and at starting I got the error efi0116 one or more boot drives need to be configured they were on raid 1 as far I can remember but it shows critical message when I put 1 or so then done and it says that Stil and I renter I can see some other stuff physically disk etc. in physicall disk I can see all 3 but in virtual disk no drives configured I think it was so now I shut the server down removed power waited 7min and replaced power and waited 5 mins so now Still that error! Any one can help me I don’t want to loose my data and don’t know what to do! Let me know if I should do screenshots! :(

RAC0501: Physical hard drives cannot be displayed. 1. Check if the host system is shut down or turned off. 2. Check whether the physical hard drives are inserted into the housing or attached to the back wall board. 3. No capable out-on-band controllers were found.

i don't know if that error was already before removing the drives(just some information):

Hostoperating: system RAC0690: No iDRAC Service Module is installed on the server's operating system. Install the service module and try the process again.

I would be happy for ny help might be some specialists who had this problem already has an idea or solution this to fix when possible without data loss! :(
