Hey there,

I've installed a brand new Samsung 980 PRO nvme m.2 in my Precision 7760. Now the system boots very slow, the DELL logo remains for about 90-120 seconds and fans start running heavily! Tried to fix the boot manager but access to bootrec/fixboot is denied. I noticed entering CMD with a flashdrive shows "x:\windows\sytem32". I have even assigned a new drive letter to the FAT32 Volume, formatted the volume and used bcdboot to create a new startentry, but there is no change.

I had installed a fresh OS with the help of SupportAssist OS Recovery. All drivers are updated to diagnostics do not show any issue. Before installing years to everything ran smoothly.

Hopefully someone can help. Thx in advance!
