Issue with installing CentOS 7

Post by RasBigz » 2018/01/26 01:55:27

Greetings everyone & thank you in advance for the assistance! So, I had my laptop setup for dual booting Windows 7 & CentOS 7. CentOS got corrupted, so I'm finally coming around to fix it. When I am trying to install the OS, I'm getting the "Error checking storage configuration". Can someone PLEASE walk this newbie through the steps to fix this and re-enabling my dual boot option.

Does your Windows 7 still start up OK?

Replying to Ancientnoise... No, my Windows7 does not start properly either. I believe I deleted the MBR also, which probably means that I need that part also. :?

Can you boot from a linux boot CD/DVD and run fdisk -l as root?
If it shows some partitions then the (linux/GRUB) boot loader part may be missing, and your windows installation could still be intact.
I'm not familiar dual boot windows+linux, but I seem to remember that there are windows tools to recreate the windows boot loader.

Replying to Tunk... I ran the fdisk-l as suggested. I see Device: /dev/sdb1; Boot: *; Start: 2048 End: 30218841; Blocks: 15108397; Id: c; System: W95 FAT32 (LBA). I think this means I did have some my drive still... Windows part. Please advise.

Replying to Tunk... ran diagnostics & it suggested that I run chroot /mnt/sysimage. Tried to rerun the installation and it is working!!! :) Fingers crossed... I should be able to configure the dual booting again!!! Will keep posted...

Update: I got the CentOS 7 installation working... edited the /etc/grub.d so that I have the option to select Windows 7... BUT when I select it, I get this error: hd2 cannot get C/H/S values. Press any key to continue... :( Can anyone please advise what am I missing and how to get it back?

I think that in GRUB the disks are numbered from zero, i.e. hd2 should be the third disk. Is that correct?

Grub should be able to find the Windows-Installation automatically when using "grub2-mkconfig".

What's the output of

Code: Select all

os-prober
?

Sorry for the late reply... :D I fixed the issue! The wrong hard drive number in 40_custom.
