Inaccessible boot drive problem

[thepeanut123]

Using my old hdd 1 tb seagate that had windows 10 installed from my old prebuilt pc however when using it in the newer build I get a BSOD that says inaccessible boot drive. My question is how do I fix this as this wasn't a problem before as I just used my old pc just fine yesterday and to fix the issue without deleting any saved data on the hdd many thanks in advance

Do a clean install of Windows. Otherwise, you will have probs, sooner or later

The old system / hardware wont be the same as the new system.

And all the drivers wont be the same as the new system's drivers either
