How to Repair Error 17 in Grub

1. Boot the computer, then enter the command to enter BIOS displayed at startup. The command to enter BIOS will be displayed on the initial splash screen and must be entered before the splash screen goes away. The BIOS command varies depending on manufacturer. For instance, Compaq computers use 'DEL' while most Dell computers use 'F2.'
2. Locate the HDD devices in the BIOS menu. All HDD devices connected to the computer should be detected by the system BIOS. If a drive is missing from this list, check that the device is properly connected. A correctly connected drive that is undetected could indicate a physical problem with the disk that may be unrecoverable.
3. Write down the initial BIOS settings for each HDD device on the system. Before making changes to a system's BIOS, it is good practice to record the initial settings so that they can be returned to their prior state if necessary.
4. Change the mode on all HDD devices to 'Auto' by cycling through the available options using the + or - keys.
5. Change the Type field of the HDD device to 'User' by first highlighting the field by tabbing over to it using the up and down arrow keys, and then cycling through the available options using the + or - keys. Note that not all BIOS will have a Type field. If your system does not use the Type field, disregard and proceed to the next step.
6. Press 'F10' to save your changes and 'Esc' to exit the BIOS. The system should now boot correctly without Grub error 17.
