The grub hard disk error windows 7 install used all of the default settings. When I try to boot the machine, I get "Grub Hard Disk Error" I've tried every setting available in the BIOS for the boot HD, and nothing works. If I put in the Ubuntu CD, I can "boot from the first hard disk" with no problem, and the file system looks like it's all there. What do I try?

To sum up, I had two HD on my machine: one with Ubuntu GNOME 14.04 and http://askubuntu.com/questions/571295/how-to-solve-grub-rescue-and-or-mounting-hard-drive-problem another two with Windows 7. I had to connect another HD with windows replacing the other one with windows, copy some files from this hard drive. After that, I connected only this HD and formatted it. Ok, no problem beyond a grub-rescue shell appearing, but I solved changing the boot order of the hard drives (no idea how). Now, I need to pick up those files and place them into the windows hard driver, but again the grub-rescue shell. This time, I tried almost everything, mount it using a Live CD, some stuff in the grub-rescue, changing boot order, nothing. It's not even mounting it when I use windows or a live cd. In that first case, I hadn't a usb stick, but now I got one, I only want to mount the linux hard driver and copy those files. Yes, I've searched for questions like this one here but didn't solved nothing... So, here are some information and things I tried: ubuntu@ubuntu:~$ sudo fdisk -l Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors Units = sectors of 1 *

I believe I installed Ubuntu over Windows on my Acer netbook. I then grub hard disk tried to install Linux Mint, but it wouldn't start installing. I turned the netbook off and back on. Now I get the error. I have read a lot of other questions like this, but in my case I cannot boot a CD. If I put a Ubuntu CD or a Linux Mint CD into my external CD/DVD drive and change my BIOS to boot the CD-ROM first, it just gives me the same error screen.

Contents Introduction Booting via GRUB The minimal Linux method Using a CD Using an internal hard drive See Also Introduction PCs use a system called the BIOS (Basic Input/Output System) to start the machine. A modern BIOS (written after 2002) usually contains USB drivers and a boot from USB option but older computers often don't have these features. There are two common problems: They may lack a BIOS setting to allow booting from USB. They may not recognize USB drives initially, and may require operating system drivers to accomplish this. An alternative for older machines is to let the BIOS start a minimal Linux system on a BIOS supported drive such as a floppy disk, CD, or HD, and then transfer control to the USB drive to continue booting the full operating system. A minimal Linux system contains the necessary USB drivers to continue the boot process. Note: If the computer was made between 2002 and 2005, it may contain USB drivers, but not an option to boot from USB. In this case the GRUB bootloader can do the job directly, without the need of an initial Linux system. Booting via GRUB The easiest way to boot from a USB Drive is to boot via GRUB. To check if your BIOS is able to detect the USB drive and hand it over to GRUB, just run GRUB from your hard drive if it already installed, or from a GRUB boot floppy or CD. At the GRUB menu, hit the C key to enter command mode. Now search for your USB drive, using the root command to choose a drive/partition and the find command to see if you found the right one. You can go through your devices like in this example: grub> root (hd0,0) # first harddrive, first partition grub> find /[tab] # type the slash then press [tab], and it will try to list files on this partition Error 17: Cannot mount selected partition # Oops no file system he
