I am using Ubuntu 16.04.I have created a bootable usb for my friend using unetboot in my laptop. But when I turn on my laptop it goes to unetboot option with default and tab option thing and I cant get my laptop to open. I don't have any bootable usb or cd on my laptop. My Ubuntu wont boot. Please anyone help. I have some urgent works to do in my laptop.
- Please shutdown the computer,
- and after that unplug the USB pendrive,
- and after that boot the computer again.
Maybe this makes the computer boot as usual again.
If it did not help, it seems Unetbootin used your hard disk drive as a target. What happens when you try the different options in the Unetbootin menu. Maybe it will start a live Ubuntu system, and you can use that system until you fix the problem.
For example, you can create a USB boot drive, boot from that drive, and repair the bootloader in your hard disk drive.
Maybe you should use another tool to create a USB boot drive. In Windows you can use Rufus or Win32 Disk Imager. In linux you can use mkusb.
If your computer does not start from its Unetbootin menu, I suggest that you borrow another computer, and try with one of these other tools, and this time, please check and double-check, that you will write to the USB pendrive, and not to some other drive. (mkusb was made in order to help identifying the target drive and avoid mistakes.)
