Owner, you can do this:
+ Use USB system to format C drive and then reinstall Windows 7
* If you can enter the system normally after the installation is completed, and you can enter Ubuntu normally, then everything is OK
* If you cannot enter Windows and Ubuntu normally after the installation is completed, then this is a hard disk boot problem. You can do this
- Select the hard drive partition under your USB system, then select Rebuild hard drive boot on the top menu bar, and then restart
- If you can see at least 5 startup items normally at this time, congratulations, everything is OK
- If you can’t see it (unlikely), there are two possibilities:
1. Failed to rebuild hard disk and boot
2. Use mini system to enter the hard drive, back up all data, reformat the hard drive...and then reinstall, first install Win7, and then install Ubuntu
Sir, please try it out
I can enter the welcome interface, but win7 cannot enter the desktop. It should be a problem with win7 and has nothing to do with ubuntu. It is recommended to back up important files, then reinstall win7 first, and then reinstall ubuntu.
Ubuntu uses grub boot, the general steps (in the case of one disk):
1. Reinstall your win7 (if necessary to join);
2. After installation, you should only be able to enter win7. It should be because the grub boot information is gone, so the third step
3. Use an ubuntu disk, or other DOS with the grub4dos program, manually enter the kernel into ubuntu, then go to boot/grub and reinstall the grub boot information
After the welcome interface, the screen goes black and only the mouse is visible. Is it a virus?
It doesn’t look like a booting problem. If there is a booting problem and you cannot enter the welcome interface, the possibility of getting a virus is smaller.
If you reinstall win7 mbr it will definitely overwrite the ubuntu boot.
You can first use live USB to install ubuntu in a USB flash drive, and then install ubuntu from the USB flash drive. Grub is compatible with mbr boot, and then install ubuntu again and take a look.
I just installed a new Ubuntu system to coexist with Win7 last night!
The easiest way to reboot an Ubuntu system is to use a software called easyBCD,
Enter the software interface
Click on the left column to add a new entry
Select Linux-grub2 in the pop-up window
Select the Ubuntu system item
Restart your computer and you will see two system options
Hope it helps you
The boot of win7 installed later will overwrite the boot of Ubuntu without any doubt, that is, you can only enter win7.
