Dual Boot Debian +W7:recovering Access To Encrypted Partitions

I have setup a dual boot system with Fedora 21 and Arch Linux. The problem is that Fedora doesn't see my encrypted Arch installation. The installations are on separate partitions and do not share anything apart from hard disk space. I have run the following commands as root in Fedora:

Code:

grub2-install /dev/sda

Code:

os-prober

Code:

grub2-mkconfig -o /boot/grub2/grub.cfg

When I rebooted, Fedora was the only OS entry showing in the GRUB menu.

There was a suggestion from one of the members of the Arch forums that I should write the entry myself into /etc/grub.d/40_custom and then re-build the grub configuration or take the Arch entry from Arch's /boot/grub/grub.cfg and just paste it into the 40_custom in Fedora and rebuild.

How do I boot from a live Arch USB stick into the installed Arch and do as stated above? How would it work? Thanks in advance for your replies.

Hi, yesterday I decided to install Deepin in a dual boot. I later decided I no longer needed/wanted it so I deleted the partition. Apparently I had grub on that partition as well, and now my laptop only goes to grub rescue and will not boot.
I have an acer aspire v5 touch. Removing the hard drive is not an option. I have tried to access UEFI but my computer just beeps and goes to grub rescue. I have grub rescue disk on a flash drive, I used unetbootin to do that, but iI cannot get to any boot menu (f12), and when I use ls (hd0)/ I get a unknown file system error. Please help, and sorry for my grammar/formatting, I'm on mobile.
Tl;dr: Deleted partition containing grub and deepin, now can only get to grub rescue, and I keep getting an unknown file system error, please help.

I have an old debian distro installed on hard disk. The distro is on sda1 partition. I also have Win7 on a seperate hard disk which is on sdb1.
When I boot up, GRUB bootloader opens up and gives me the option to select either OS.

So I recently installed a new debian distro and put into my sda2 partition.
But now when I boot up, GRUB only sees the new distro in sda2 and I can't access the distro in sda1 or Win7 in sdb1.

On one thread someone said mounting the partitions and then using 'update-grub' will resolve the problem.
I tried it and re-booted, but GRUB still only offers the newly installed distro in sda2.

Can someone help please?

Machine is booted into Grub Menu
I am using rescue linux

by doing fdisk -l

it shows
Disk /dev/sda : bla bla bla
Device Boot
/dev/sda1 *

so i install grub using this command in shell

grub-install /dev/sda1

it shows

installation finished. No error reported
This content of the device map /boot/grub/device.map


After re-boot it again shows grub menu

I've just compiled my own kernel (debian), but I have no idea how to boot it. I don't know how to get to the grub menu. I've tried holding shift down at start up but it doesn't work! When I hold down esc it asks me what I want to boot?

I've read that I have to edit the file /etc/default/grub - but I can't since don't have it..

Does anyone know how?

After repair-boot fhe problem continue.

Hello there,

I tried to install kali alongside windows and did it wrong probably. Now whenever I boot, grub loader sees only Kali and Free-DOS and doesn't see Windows.

I can still see the Windows partition in Kali and access the files however.
Searched online for a solution and saw that boot-repair could help me, however because some new update issue I cannot install it under Kali directly( see below link, it doesnt work for me).
askubuntu.com/questions/449818/cant-find-boot-repair-package-for-the-newest-version-of-ubuntu]

Long story short, I downloaded the iso version of boot-repair and tried to burn it onto a live-usb, but it doesn't load. All I get is a black screen with a terminal line running where I can't do anything.
I burned the iso using the terminal and the command below.
sudo dd bs=4M if=file.iso of=/dev/sdc
I burned the iso using unetbootin a couple of times and the same issue.


Any ideas? am I doing something wrong? How can I burn the iso disk to a live USB to run boot-repair? Or any other alternatives?

PS: first time linux user, I have no idea what am I doing so please be patient with me.





This is my output for running sfdisk -l.

Hi All,

I recently decided to tryout Linux and dual booted my laptop (originally just had windows 8) with Xubuntu. Now I want to try out Kali Linux. So I downloaded Kali and made a bootable USB, the problem is that when I try to boot from the USB it just brings up the grub menu asking me to select Xubuntu, Windows etc. I've changed the boot menu in the BIOS but that has no effect.

I've tried booting into windows and the restarting by holding shift but when I select the usb option it just says:

"system doesn't have any USB boot option. Please select other boot option in Boot Manager Menu"

and then returns to the grub menu. I don't understand because I used a bootable usb to install xubunto?

I'd be really grateful if anyone can help me out with this!

Thanks

Hello All. This is my first post here. I am worse than a newbie; I'm a PC dinosaur! Not joking either.
Recently got a Dell Inspiron 3048 with Windows 8.1 pre installed. As I am a die hard XP user (my other PC is a Dell Dimension 2400), and seeing that PC's days may be numbered, I want to start using Linux, and decided Mint 17.1 would be first on the list.
Ordered a Linux Mint 17.1 boot disk and went to install it. At the option for a dual boot with Windows, I got lost, and did not understand the "other" choice versus making Linux the only OS on the PC. I wound up wiping my HDD and lost contact with Windows 8.1. Fortunately, the Dell Tech I got at Dell Support was able to walk me through getting Windows back up, but the only way I can now access Mint 17.1 is with the boot disk, but there is no set up options as it is already set up, even though incorrectly for a dual boot.
How do I wipe out Linux without losing Windows 8.1 as well so I can re install Linux and this time make the correct selection for a dual boot?
Anyone willing to respond please do so small and slow so I can follow.
TIA.
BTW, I have tried installing Zorin OS 9 Ultimate on my XP machine via DVD and USB, but I can't get past the f1/f2 loop, even though I have reconfigured my boot sequence according to the drive I'm installing from. Zorin support has been MIA on this. Anyone having a similar problem?
Cheers

After creating a bootable usb using Universal USB Installer. I booted up the sytstem (Dell Inspiron N4110) F12 boot on usb, did the install, everything went well until after copying files and then the error message that "The grub-pc package failed to install into /target.. So i continued without a boot loader and now am trying to figure out how to get it back.
Previously i did a perfect dual boot of Kali Linux wherein the Grub boot loader was present. I did however uninstall Kali, reclaim HDD space, and even use EasyBCD to remove Grub(i believe).
Also worth noting is that before this dual boot with pignuy and after uninstalling kali linux i did a complete reinstallation of my windows 7 system using the recovery HD.

Now i would like to know how i could get grub boot loader back onto my system so that i can boot up Pinguy OS. Thanks
