Encounter difficulties accessing unknown file systems during PC startup.
Encounter difficulties accessing unknown file systems during PC startup.
While working on splitting my SD card yesterday, I unintentionally affected the partitions on my hard drive. My main drive holds all my files and Windows 7, while a smaller drive contains Ubuntu 10.04. During the process, the changes didn’t save properly, causing the system to freeze. I had to stop the Partition Wizard. Now I face two issues: first, the SD card partition that was set as primary in Ext3 format appears as a logical volume, and second, I mistakenly asked the wizard to erase my Linux partition. The machine still runs on Windows 7, but when I tried to boot again today, it displayed an error directly under the system monitor without entering the GRUB menu. I’m not familiar with Linux or Unix concepts—I’m just trying to get Windows running from the untouched HDD drive. Please help! I don’t have any expertise in Linux or Unix, and I’m unsure about using commands like ls. Can you assist me in resolving this?
I believe a serious issue occurred here. Grub is your main component, bootloader or whatever, and because it's your primary bootloader, it should start Linux first. Since you erased your Linux installation, there’s nothing there. Before that, your main Linux partition or EXT3 layout was recognized as logical, which might explain the missing file system error... Or perhaps you completely wiped everything on your hard drive, so the BIOS isn’t being found... I’m not certain, I’m currently looking into it, but I’ll try to assist you and I know it.
If you find the video uninteresting, consider using these instructions: setboot=(hd0,msdos5), then set prefix=(hd0,msdos5)/boot/grub, followed by insmod normal and normal. If this doesn't function, swap all fives with ones!
Thank you for your quick responses. Unfortunately, the standard boot/prefix/insmod commands didn’t function, so I asked a friend to create a boot-repair disc. If anyone else faces this issue, look at the video they shared—it helped me. Make sure both PCs use the same Windows version. I attempted to fix my Windows 7 Home Premium 64-bit PC by using a disc made from a Windows 7 Ultimate 32-bit PC, but that didn’t work either.
