Grub rescue. I check also BIOS. what happend? can you help me? please explain what can have to do such situation? thanks in advanced.
If you have another drive you can swap in, try installing again. Also, download Memtest86 and let it run for 30minutes at least to make sure memory is not one of the many possible problems.
I did that step. i opened case and replace sata cable to another port and run PC it worked... why it causee above mentioned trouble, what is reason of it? thanks for supports.
corrosion is the problem. All these tiny little contacts are coated with a very thin layer of gold a few microns thick. If you frequently plug and unplug such cable, the gold cover disappears very quickly and a copper or other metal comes to surface. When oxygen hits this open surface an insulator gets created and no more current can run at that place to your disc for example. using a different port sometimes solves the problem as you could see.
Gurb rescue... You must have a linux install somewhere and the boot partition is damaged/removed. Grub can'T access is, that's why you have that message.
