hiiii all
I had installed Windows 7 on /dev/sda1 and /dev/sda2 and then I installed Centos 7.
Since then I cant find Windows entry in the Grub.
And i had tried to use all kind of solution found on the net I still cant see any entry.
I had edited 40_custom script adding:
cat <<EOF
menuentry "windows 7" {
insmod part_msdos
insmod ntfs
set root='hd0,msdos1'
search --no-floppy --fs-uuid --set=root FCDAE998DAE95006
chainloader +1
}
EOF
then this command grub2-mkconfig -o /boot/grub2/grub2.cfg
[root@localhost]# grub2-mkconfig -o /boot/grub2/grub2.cfg

Please Help,
I have a Windows 7 and Fedora 20 dual boot pc .
Today i deleted the fedora partition from windows disk management and then restarted my pc.
Now i am stuck in the 'grub rescue > ' screen ...... It is showing 'no such partition ' , after searching through the internet i tried these commands......
grub rescue > set boot=(hd0,msdos6)
grub rescue> set prefix=(hd0,msdos6)/*boot/grub
grub rescue> insmod normal (after this line ,i am getting the error , grub rescue > unknown filesystem)
grub rescue> normal
Don't know what to do ,but i want to get back to the windows os first ,also i don't have the windows or fedora live cd . My Windows recovery is stored in my pc hard drive....... plzz help so that i can resolve this issue
I am going to attempt to dual boot both fedora 17 and fedora 21, as my printer can print from FC17 but not from FC21 - posted about this issue in the hardware forum.
I am rather surprised at the level of competence of people posting here, even though it says newbie forum - so I think that this is possibly where I belong too.
I have set up grub to see my fedora 17 kernel - the only problem is, that the root filesystem needs to belong to the fedora 17 kernel as opposed to the fedora 21 kernel. I can't see myself changing fc 21's fstab to have the old lv root device mounted - as /etc belongs to the root partition of fc 21.
I did change the device to reflect the old kernel's root lv partition in the /etc/fstab (fc17), but this doesn't seem to do it.
Does someone know what I am missing?
Hello all,
I was screwin' around with Arch Linux. I'm interested in it but not more interested than my Kubuntu running KDStudio.
I didn't realize how much prep. their is and the fact that Arch does no prep. Anyway, I stopped trying to get it to run when I realized I had to pre-partition and set up a swap.
Now however grub does not boot into the KDE desktop. It boots into Kubuntu but with no desktop.
Does anyone know how to fix this, I would not like to have to re-install the whole system. I think there must be a fix, I'm not sure exactly what Arch did, gparted doesn't show anything.
I have tried installing a Ubuntu OS onto a partition (sda3).
When I had difficulties with the install, I decided to delete everything from the partition.
But now when I boot the computer, I get taken to the 'grub rescue' prompt.
I have tried to find grub in my other partitions (sda1 and sda2).
However, the command 'ls (hd0,msdos1)/' for example, does not show a grub directory.
It must've transferred grub to sda3 somehow and now I've deleted it.
I have debian live USB and am trying to install grub with:
Code:
apt-get install-grub /dev/sda
But I get the error message:
Code:
bash: grub-install: command not found
So now I don't know what's going on. Can anyone please help?
I have made a change to GRUB2 bootloader in etc/default/grub.
Now I need to run 'update grub' for the change to take effect.
However, the 'update grub' command on the terminal is giving this error message:
Code:
root@debian:/# update grub
bash: update: command not found
Can someone please explain why this command is no longer working?
I've had to make a change to grub because I tried to install a new distro which meant I had to alter grub.
The install wasn't successful so I deleted the grub file and then re-installed it.
The re-installed grub needs a change so I can get sound on my pc.
However, I can't add these changes because the 'update grub' command doesn't work.
I've checked the grub file with another debian distro and they are both the same.
So now I don't know if I need to check if a different grub file is the problem or anything else.
Can someone help?
Hi
My machine was a dual boot debain + W7. The debian had LUKS encryption and LVM.
I had to re-install W7 and now there is no access to the grub menu and of course to the debian installation.
I tried "boot repair disk"
http://sourceforge.net/projects/boot-repair-cd/
, but it couldnt access the encrypted volume. It did generate the following output:
paste.ubuntu.com/10591353
Would appreciate help how to get the boot repair disk to access the encrypted partition and recover the grub menu
Thanks
I clean installed Antergos 64bit (GNOME 3) on my iMac, and now need to boot the OS X DVD that came with the computer to format and restore. The ultimate goal is to keep this machine for dual-booting (which I can take care of) since there are simply things I need from both operating systems. If only Antergos or GRUB would boot from the DVD to kick-off the process.
What have you done so far?
It made sense to install rEFInd on this machine, since that was the program that helped OS X boot the Antergos image from my USB drive in the first place.
I followed the steps laid out in the Arch Wiki.
First, by using the refind-install command
Then used the refind-install --usedefault /dev/sda1 command to "also install rEFInd to the default/fallback boot path".
I shutdown, and booted the Mac up in hopes to catch rEFInd's splash screen, but to no avail. Only the Antergos/GRUB screen, and then into Antergos as usual.
(This began a hopeless cycle of re-installing, and rebooting which lasted quite some time.)
Afterwards, I tried manually installing rEFInd using the following commands from the Arch Wiki:
Quote:
cp /usr/share/refind/refind_x64.efi $esp/EFI/refind/
efibootmgr -c -d /dev/sda -p 1 -l /EFI/refind/refind_x64.efi -L "rEFInd Boot Manager"
Also, I installed the mactel-boot utility from the AUR.
And according to the efibootmgr utility, rEFInd was now first in the boot order:
Quote:
BootCurrent: 0002
BootOrder: 0004,0003,0002,0080,0001,0000
Boot0000* ubuntu
Boot0001* rEFInd Boot Manager
Boot0002* antergos_grub
Boot0003* rEFInd Boot Manager
Boot0004* rEFInd Boot Manager
Boot0080* Mac OS X
Boot0081* Recovery OS
BootFFFF*
After shutdown/power-on, the machine displayed alot of white-colored "clearing node" text, before tragically booting once again into Antergos/GRUB.
I've also read How-to Geek's guide on re-installing OS X on Mac, yet the tutorial never mentions how to restore it from Linux.
Conclusion:
What piece of this puzzle am I missing? Would creating a LiveUSB of OS X be an easier route than this DVD? Is there a GRUB command I'm not aware of that can change the boot order?
I'm almost certain rEFInd is not the only way Linux would be able to boot this OS X DVD, it's just the only way I've known how so far.
I can clearly see the Mac OS X boot option in efibootmgr as Boot0080*, so at least it's being recognized. When Antergos boots to the desktop, the OS X DVD is displayed as "WindowsSupport" if that helps.
I'm out of my element and am at an impasse, your help will be appreciated.
PLEASE & THANK YOU
Hello, I have a laptop with no operating system and I want to put the Arch OS on it. How do I go about doing that? Do I just burn the ISO on a CD and stick it in while I boot up?
Thank you...
Machine is booted into Grub Menu
I am using rescue linux
by doing fdisk -l
it shows
Disk /dev/sda : bla bla bla

This content of the device map /boot/grub/device.map
After re-boot it again shows grub menu
