Hello everyone,
I have problems to log into systems recently. Here is the description of the problem:
I installed windows and ubuntu linux in my laptop, sometimes after I pushed the power button, the screen of the mainboard showed up, and then the whole screen came to grey without any letter which supposed to be a GRUB loading stage to let me choose which system I would go to. But if I put the installing disk of the ubuntu into the disk drive and reboot, this time I could see the selecting menu of the grub. Then I can log into the system..... Sometimes it just OK.
Could someone kindly help me on this? Thank you in advance!
