Elitebook 850 G1 wont boot after mainboard replacement
Product: Elitebook 850 G1
Operating System: Microsoft Windows 10 (64-bit)
Hi, we've just had a mainboard replaced on an Elitebook 850 G1 and now Windows 10 wont start. HP tech's arent being too helpful as the machine came with Windows 8 and was upgraded. I get the preparing automatic repair screen and then the advanced troubleshoting options. Startup repair gets nowhere. In Command Prompt cant see any partitions. DISPART/list disk says "There are no fixed disks to show".
I booted to a Windows 10 bootable USB and a DVD and same issue.
At the suggestion of HP I tried setting boot mode to Legacy and UEFI Hybrid modes and no different. I tried changing the boot order with M2.SATA and SATA drive and no difference.
I booted to the original Windows 8 recovery DVD as far as selecting a drive/partition to install on and can see the 4 partitions and all looks OK.
I'm running out of ideas and really dont want to do a full reinstall as the machine has a lot of app's and would need some very time consuming configuration
