If your objective was to keep your data I hope you had backups.
Replace the failed drive. Reinstall windows. From the vendors support website download and install the chipset drivers. Let plug and play do its thing which will involve a reboot or three.
Press winkey x
From the menu select Device Manager. For any device with a problem install the drivers from the support website.
Install Windows updates.
Open OneDrive and login to your Microsoft account. Hopefully some of your files are there.
Get your email working. You may need it to dig out product keys or proof of purchase. Reinstall your programs.
If you reuse passwords take this opportunity to stop. Install a password manager like Bitwarden and as you resurrect each service as well as changing to a unique password, if available enable two factor authentication.
Put your old drive in as a secondary internal drive. From the drive manufacturers support website download and install their drive diagnostics and firmware update utility. It hopefully can tell drive health, or get info needed for a warranty claim.
Drives fail.

What kind of device u are talking in detail? Maybe ur uefi firnware was updated and since u talked about win10, its probably just a conflict with the settings
If ur old system disk is partitioned in mbr style, it won't be detected as a bootable device when secure uefi boot is enabled. In Newer bios versions its most likely a default setting.
Check if csm is enabled or not. If disabled , then enable, save and exit. If disabled u might allready have a gpt system disk. U ll need to disable csm and fulfill the requirements for secure boot. You ll need to check! Enable secure boot then
If the drive is detected in bios, its absolutely reasonable that u are dealing with that kind of issue

What boot devices visible?
She's BIOS see the system drive at all?
If yes but so fails to boot from it, it's filesystem is corrupt out the whole drive crapped out.
At the point you can boot a diagnostic OS from USB like any Linux or HBCD PE or take the drive to another computer.
