On my test systems, I had formatted /dev/sda1 by creating new file system layout (mkfs.ex4 /dev/sda1).

Now, you can install new kernel packages as required. Reboot the system and check if system boots up fine & /boot is on /dev/sda2 partition, if so then you are all set & done. After this toggle the boot flag so that /dev/sda2 would be marked as bootable and mask boot flag on /dev/sda3 using fdisk command. Edit nf file on the /dev/sda2 partition so that it points to correct splash image and root directory as shown below: Once this is successful quit from grub prompt. Grub> setup (hd0) -> this would setup bootloader on the required partition Now, inside grub prompt run the below commands: Install the required boot files (stage2.) on /dev/sda2 Edit /etc/fstab and add new entry of /dev/sda2 and comment out old boot entry. Copy all files from /dev/sda3 to /dev/sda2 If you wish to get this done then you may refer the below steps (risky and Red Hat would not recommend this.) - Make a backup of boot and it's partition layouts.
I had tested this by moving boot partition from /dev/sda1 to /dev/sda2 which worked fine on my virtual machine running with RHEL 6.5, but ran into some error initially "file not found" which I was able to replicate later properly without much hiccups. Again, could be resized from the partition end not from the beginning provided there is empty space in the specified partition layout.īut I notice that there is /dev/sda2 with size of 5GB which I guess un-used, why don't you make this as boot device if this not targed to be used for anything else. Yes, re-sizing partitions is highly risky and sophisticated.

I have resized the LVMs using command line but I'm not sure how to resize /dev/sda3 which is /boot I need to expand the size of my /boot partition due to a kernel upgrade. However, if only the partition table has been corrupted, testdisk will very likely be able to easily reconstruct it.├─VolGroup00-LogVol01 253:0 0 11.7G 0 lvm If the data on the disk is very valuable to you, you might consider contacting data recovery professionals rather than trying to fix it yourself. If you have anything important on the laptop, you should make a backup image of the complete disk before trying to fix it in any way. If you find that the partition table has been corrupted any more severely than that, stop. The partition that should be marked as bootable will be the smaller "system partition", not the partition that appears as "drive C:" in Windows.

Note that Windows 10 normally uses more than one partition, even on MBR-partitioned disks. Use that tool to make sure that the partition table has not been corrupted, and if more than one partition has been marked as active, remove the unnecessary mark. Apparently your system's BIOS checks for that and will boot from the hard disk only if exactly one partition has been marked as active.īoot from any external media that has a tool that can modify partition tables, e.g. The MBR partition table has a setting that is used to mark one of the primary partitions on the disk as "active", i.e.
