Can't access Windows 10 in dual boot.

[davidjj2]

A month ago, I installed a dual-boot of Windows 10 and Ubuntu 20,04 on my new 17ca1500 laptop, and it worked well for a few weeks. Then, last week, I found I could not get into Windows 10. The boot screen worked OK, and so did the Windows login screen; but when my usual desktop picture came up, there was nothing on it. No apps, no control panel, no file manager, just the Windows start button, and that did not work. The desktop seems completely dead. Ubuntu is still working normally, and I can see the Windows files in the Files section, so they must still be there, but I can't reach them. Does anyone have any idea what might have happened?

I'm sorry, but HP does not provide support for Linux distros.

IF you replace the preloaded Windows OS with a Linux distro, or add a Linux distro, then you assume full responsibility for maintaining that -- including solving any problems with booting the other OS and/or installing the other OS.

Modern PCs with UEFI, instead of the older BIOS, are especially difficult to install because you have to go into the UEFI settings and make several changes before you can even boot from a USB stick -- and we are unable to assist in that work.

Your best bet for support now is to contact the support forum of the distro you are using.

Since you are using Ubuntu, go here: https://ubuntuforums.org/

Good Luck
