your boot partition contains efi folder. if you use efi booting grub donot use /etc/boot/grub/grub.conf file. so it is empty. inside efi folder you have a grub config. also from efi partition you may use grub2 hence grub2 has grub2-mkconfig command to build configuration.

You may have more success with UUIDs with external drives (as drive namings such as sdb1 are not permanent for external drives); To find the UUID of the drive in question, execute ls -l /dev/disk/by-uuid/, then replace the line in /etc/fstab which you had previously to use the appropriate UUID, eg: UUID=ABCDEF0123456789 ...

On the host, you have to create a second virtual network that contains your iSCSI NIC's. Then you can add a NIC to the guest attached to that network. That gives you access to the iSCSI network inside the guest. However, Hyper-V does not support booting guests directly from iSCSI. You have to chainload in to iPXE or something similar. Hopefully you already ...

In grub, edit the kernel command line and append  systemd.unit=rescue.target. The system will then boot to single-user mode with a shell and you can begin checking the logs to determine the actual cause of the problem.

This is when the install is on the Solaris machine; In order to use the USB stick as a boot media, you will need to have the OpenBoot version higher than 4.27 (when you get to the ok prompt you see the banner that tells you your Open Boot version).. If that condition is met, you can try to use the USB stick prep by the link provided in the first response by ...

Using grub-install /dev/sdX is probably how it is intended to be done. However, I just had to rescue a CentOS 6.4 server that had that setup, but now froze at boot after its other bootable RAID 1 disk was replaced some months earlier (the server had stayed on during the meantime). What solved the issue in my case was grub-install /dev/md0, where md0 is the ...

I see the same type of problem with my SuperMicro X7DCA-L with the latest BIOS (R1.2a), though I don't even have to change anything for it to happen. The machine just randomly decides to move things out of the excluded list and/or change the boot order. Sometimes I can reboot several times in a row before it happens, but it happens regularly. I'm assuming ...

This turned out to be a very interesting question. There are lots of links out there on this topic but they are ambiguous in describing the difference/relationship between the two. Best description I've found of the hard drive configuration for a Windows OS is this one: http://www.ntfs.com/hard-disk-basics.htm. It appears that MBR and Partition Table are ...

For me the solution were missing "dm-mod", "dm-snapshot" and "dm-mirror" entries in /etc/initramfs-tools/modules. I took me quite some time to fight this issue as the error messages were talking about "mdadm" and raid - so how should one guess that lvm is the issue. My setup: sda -> sda1 (0xfd linux raid autodetect, 500MB), sda2 (0xfd linux raid autodetect, ...

It occurs that it is not necessary to unpack the ISO images at all to either alter or remove/add contents; you can merely use a suitable archive managing tool (such as 7zip) to view and alter the contents before making suitable copies of the ISO as desired. As for the background image - it exists as a 640*480 in syslinux/ocswp.png - replacing this with ...

I've used that method you're talking about to set ulimit and umask for files created by the Apache user. Meaning, I've edited /etc/init.d/httpd and included a umask and ulimit -s configuration there, that solved my issue so I guess it's a good solution. It didn't have any impact except for the expected one.

I had the same issue as B14D3 using the same version of Xenserver and VMs with Centos 6 and 7. I need to resize the file system using gparted, to accomplish that I need to boot from the live dvd. I can't find the "Start in recovery mode" as referenced on the answer above. I guess it only works with Ubuntu or another OS. I've found the solution for this ...
