Hi , I have a z820 station. The windows 10 auto update screwed up my system. I can't go to repair mode either. So, I created an installation USB and try to boot from USB. In BIOS , I went to the boot menu and selected the my USB device as boot device. The screen did show boot from USB message and then it always stuck in the blue window screen after showing a black screen with one cursor flashing for 20 seconds around. It did successfully load the installation menu for only one time and failed most time. I'm not quite sure if this is a software issue or something wrong with the hardware. Very appreciate your tips.

Maybe, wait for 5 minutes, to see if the computer is "working", but not making any updates on the screen.
Does your computer have a lamp that lights-up whenever the disk-drive is active? Is that lamp blinking, erratically, or is it "100%-on" (to indicate that the disk-drive is very busy) ?

Thanks for the response.
I tried ubuntu installation disk and windows 10 installation disk. Now , I'm pretty much sure windows 10 boot has a serious bug. I have no issue start up from ubuntu installation disk and ubuntu can recognize my SSD properly. However, the windows installation disk either can't be loaded or can't recognize my SSD.
If I'm not wrong, the bug introduced by windows team last one year turn to bigger. Earlier, their auto update screw up my whole system and I can use repair mode at least to restore them. Later on, I noticed I even can't go to repair mode anymore. It seems they don't realize the bug in their new version and let the issue turn worse.

@Jimh10 -- a "file-system" must be written onto any HDD/SDD by "initializing" the device, but not all file-syistems creating when using Ubuntu are recognized by Windows.
If you open "Disk Management" in Windows, does it show the SSD as "unformatted" or "incompatible" or some other attribute? It should detect the SSD as being physically-connected.

I think my response might confuse you. I didn't try to have dual operation systems in my computer.
My z820 have win10 installed originally. I burned a CD with latest version win10 ISO. z820 even can't start from the installation disk. I have verified disk in another computer and it is good. Basically, I can't even see the installation screen. The computer failed to start up from installation disk and immediately stuck in the logo window again(which means the boot failed from DVD drive and back to hard disk default boot ).
I used ubuntu installation disk to start my computer and I didn't have this issue.
By the way , I installed ubuntu and saved all critical files through ubuntu file manager. I have dropped all windows partition and fully migrate my z820 to ubuntu. I noticed , in another thread, one gentleman faced same issue in his z820 and he thought it was a hardware issue. I'm pretty much sure it was not.
Anyway, the win10 latest version introduced a bug which break the startup through z820. I think the issue is between z820 bios and windows 10 bootstrap .
