The kernel crashes after the update under fedora, and data is copied under LVM.

Two days ago, I clicked the Fedora update and did not carefully read the updates. As a result, my system encountered an error. the update task was terminated when it was not completed. after the task was restarted, the system would not be able to enter the emergencymode. I installed Fedora...

 

Two days ago, I clicked the Fedora update and did not carefully read the updates. As a result, my system encountered an error. the update task was terminated when it was not completed. after the task was restarted, it failed to enter the emergency mode. I chose to use the entire hard disk when installing Fedora for partitioning.

 

I have processed and retrieved the data in this way. it is very likely that my method is too stupid. a superior person has a simpler method, but it is good to copy the data. thank you for your luck ~

 

1. in the past, if XP had a problem, I used PE to copy data. so this time, I took a Ubuntu LiveCD and started the computer, if you want to load LVM partitions using the "utility disk tool" under "application"> "system tool", an error is always prompted.

 

2. someone mentioned a tool after google, which seems to be used to view LVM partitions. I used Ubuntu LiveCD to try to read data in lvm. I searched for the LVM keyword in the Ubuntu Software Center, find a software that allows you to view and install LVM graphically. then, activate the LVM partition under the "utility disk tool.

 

3. after activation, you can see several more disk partitions in Ubuntu. now you can copy your data. However, some file permissions are incorrect, you cannot click copy with the mouse.

 

4. since you cannot use the mouse or shell, you must obtain the ROOT permission. in Ubuntu, the ROOT user must modify the password before using the password, "passwd root", enter the password twice, and then use "su" to change the user's root identity to log on.

 

5. now, you can use the cp command to copy the file.

 

PS: The new system is centos. centos does not seem to support NTFS-format disks. you need to install it on your own. you can find the installation method online.
