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:

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

Boot Windows ARM on Raspbery PI4 from SSD via USB3 adapter

I want to test my dev on ARM devices. With an SDCard it’s too slow, Windows is unusable.

I do :

  • I build an Windows 10 ARM ISO
  • enable USB with “winpatch”
  • put on SSD (via USB3-SATA adapter)
  • use an USB ethernet adapter for internet and transfers
  • I use a USB-C PowerDelivery 65W

The issue info:

  • BOOT_STOPPED : failed to open device: sdcard
  • Bootloader 2020/04/16

It works with SDCard but too slow. What can i do ?

Why is Ubuntu 20.04 not registering ethernet on my Raspberry Pi?

When the Raspberry Pi boots up, Ubuntu 20.04 says the following:
Net: No ethernet found.
starting USB…
No working controllers found

It continues to boot up, but this means that I can not install a desktop environment on it. The ethernet port and cable work fine, and the Raspberry Pi ethernet jack lights up when the cable is plugged in. How do I get ethernet to be recognized?
Thanks!

Ubuntu 20.04 cannot boot live CD in VirtualBox

I am trying to do some testing in Ubuntu, and need a fresh VM. I am at work running Windows 10. I downloaded the latest version of VirtualBox (6.1.10) and the latest version of Ubuntu Desktop 20.04. Unfortunately, I cannot seem to boot the live CD. I see the VBX splash screen, followed by an Ubuntu splash screen (briefly) but then the screen goes black with a blinking cursor (that does not appear to register keystrokes). Doing a bit of research, it appears that the issue is usually video adapter related, but I have tried maxing out the video memory, selecting all three different adapters, enabling and disabling 3D acceleration, and tried Ubuntu 18.04 and the latest Mint, all with the same result. I use VirtualBox regularly at home on Windows and Linux with no problems. Is there something obvious I am missing now?

Ubuntu 20.04 takes too long to boot

I have recently installed Ubuntu 20.04 on my HP-notebook(intel core i-5, 8GB RAM, AMD Radeon 2GB). It takes more than 2 min to reach the login screen.

I used the command dmesg to analyze which process it taking too much time only too see the below output:

If you go to timestamp [ 67.555730] rfkill: input handler disabled] , the process just after that by the name of audit has been called so many times and took nearly 50 secs of the boot process.
