ubuntu doesn’t work :UUID=xxxx does not exitst

My computer has two systems, Windows 10 and ubuntu18.04. Today, when I tried to get into Ubuntu(I already laid it aside for about one week ), the whole screen showed pure purple for at least 10 minutes, so I forced the computer to shut down.Then when I tried to get into Ubuntu again, it showed :

Then I tried to open ubuntu in recovery mode,but the outcome was same.And I also tried this solution:https://forums.linuxmint.com/viewtopic.php?t=47594,doesn’t work either.
At last I run fsck.ext4 -y /dev/sda1(where the root is),and showed:

Anyone know how to deal with is issue?Any help would be appreciated!

GRUB not picking up windows boot manager which is in another drive

Ubuntu 18.04 LTS and Windows 10
I have a laptop that has an SSD and a hard drive
Windows is on the SSD and Ubuntu on the Hard Drive
I made a separate EFI partition while installing ubuntu using the “Something Else” option
When I boot my laptop I have to press “Esc” key to enter GRUB and it does not pickup the windows boot manager
Moreover, Ubuntu is not detecting the SSD
What to do ?
Please ask for any additional info required

Dualboot problem with windows 10 and ubuntu in MSI

I have installed windows 10 and ubuntu 20.04 on my laptop, in general it seems that everything works fine.
The problem I observe, is when I’m in ubuntu, and I reboot to enter windows, there are configurations that are reset, like configurations with the graphic card (nvidia), sound card or wifi.

Similarly, when I’m in windows and I switch to ubuntu, the first time I log in, the wifi card never works in ubuntu, I have to reboot twice for ubuntu to detect it…

I was reading that this may be due to the UEFI configuration, which should be using legacy mode. Should I format the disk, switch modes, and reinstall windows + ubuntu?

Also, in other computers I’ve had, I used to have problems changing the time, when I changed OS, but in this case, I find it curious to observe that not only the hour changes but also the minutes, I don’t know if it’s something also rare.

I’ve put all the problems together because I don’t know if they are all due to the same mistake…

Thank you very much in advance
