Windows 10 startup problems

I have a Lenovo Thinkstation with Windows 10 installed on a SSD drive.

Everything been running fine for months until this morning the while the PC is logging on started to exhibit erratic behavior, screen going blank, PC resetting and restart, etc.

Currently It won't finish logging and usually resets / restarts.

I did see a message box about a "Elby" driver. I remember installing ISO drive software, which I believe must be Virtual CloneDrive?

Is there anyway to remove this app and it's drivers from a PC's hard drive without booting to the drive?

I have another Windows 10 PC (Lenovo Thinkcentre) that I rarely use but am able to boot to it's Windows 10 installation with the SSD drive connected as a second drive.

But I'm not certain how to uninstall CloneDrive from the Thinkstation without booting to Windows 10 which I'm not able to do.

Perhaps deleting the files and folders from CloneDrives installation path? and/or try to edit the registry file from the Thinkstations Windows 10 installed on the SSD drive?

I haven't made a bootable Windows 10 disc yet as both Windows 10 PC's came with Windows 10 pre-installed.

However the problematic Windows 10 installation on the SSD drive does have a recovery partition.

I use to have older Lenovo Thinkcenters and they all came with a Lenovo Recovery partition which allowed one to save files and perform different Windows re-installations and also installed Windows using saved backups from Lenovo's Rescue and Recovery.

I think the recovery partition is a Windows 10 Recovery partition, which I've never used.

I'm currently using my second PC. I should be able to create a Windows 10 installation disc from a Win10_SingleLang_English_x64.iso previously downloaded.

The Windows Recovery Tools - Bootable PE Rescue Disk 64Bit ISO has around downloading 5 mins left so I'll give it a try first.

I created and booted to a Kyhi's disk but could not find a system restore or safe mode. So I ended up booting to Windows 10 recovery mode by trying to boot the PC three times. The third time the Windows 10 PC goes into recovery mode. It appears re-booting Windows 10 three times replaces F8.

I tried a few times going into Safe mode and over a 1/2 dozen times using system restore, each attempt system recovery failed.

I went into Windows 10 Safe mode and re-installed the Nvidia Quadro video drivers which did not rectify the problem.

I then chose to perform a system reset which basically re-installs Windows 10 while trying to save any personal files.

This didn't work the problem became worse to a point where there was no bios boot screen.

So I installed the Windows 10 SSD drive (for the P300) into another nearly identical PC, a Thinkcentre M93p.

The M93p (Thinkcentre) was able to boot to Windows 10 that was previously problematic when installed on the P300 Thinkstation.

I'm not certain what the problem is with the Thinkstation. I tried removing it's K4000 Nvidia Quadro Video adapter using the internal mb vid adapter but it wasn't able to boot to Windows 10 installed on the same SSD drive.

So I'm wondering if there's a hardware problem with the Thinkstation P300. I'll try using another Windows 10 drive with the P300 (Thinkstation) to see if perhaps there is a hardware problem with the motherboard, etc.

The P300 Thinkstation's SSD drive with Windows 10 shows it's activated when installed in the Thinkcentre M93p (both PCs have the same hardware, with the motherboards nearly the same, the P300 motherboard has a few more certification's and uses ECC memory has a Esata port but other than those aspects the mb's are the same.

However the MS Office installation shows it now needs to be activated because of hardware changes. When I try to activate MS Office it then tells me it's been activated the max. amount of times, but still seems to function ok.

I'll keep trying to figure out what's wrong. Perhaps try a fresh install Windows 10 on the Thinkstation P300 SSD drive after backing up files.

I'm sort of tired trying to repair, so will let it go for a while and try fixing again at a later time.

The Windows 10 SSD drive installed in the P300 (Thinkstation) that was problematic is now working when installed in the M93p (Thinkcentre) are nearly identical PCs. I think the only difference is the P300 has an additional stata port and uses ECC memory as it has additional certifications.

Thinkstations are normally sold to businesses whereas Thinkcentres are usually sold to consumers.

I think Microsoft removing F8 is a mistake. One shouldn't need to fiddle around and booting three times trying to get into safe mode. The service menu is something that's part of Windows 10 and not the OEM. If a service partition is installed during Windows 10 installation then you will have an option to "reset" the Windows 10 install.

Anyway I'm going to install the Sata drive (with Win 10 installation) previously installed in the M93p into the P300 to see if it still has bootup and login problems.

If able to rectify will re-install the SSD (win 10) drive back into the P300.

The SSD drive with Win 10 is version 1803, installed in the M93p shows additional pending updates I think because this is the drive that was reset from Win 10's service menu.
