Hey guys,
So running through some computers for work updating them to SSD's from old HDDs.
1st few ive had 0 issues,
Get to this computer and I can not get this computer to detect the OS, no matter what I do.
Desktop is Prodesk 400 G4.
HDD is a 1TB no-name brand.
SSD is a wd 500GB SATA.
Made sure both are GPT.
I've tried going to legacy mode to boot to SSD, however every time I attempt to enable legacy boot and disable secure boot,
it reboots, Beeps twice, and just gets stuck on a black screen. After resetting, I can usually get back to the bios, however, every time legacy boot is back disabled and secure boot is enabled.
I've tried using a Windows installation USB to do a recovery on the OS, but the drive isn't detected. If I go to install win 10 on the SSD it shows all partitions are there but as soon as I go back to recovery the drive still doesn't show up.
I can put the old HDD back in and it boots to windows with 0 issues.
Any tips to get this SSD installed without losing this user's data?
