Installed Ubuntu 12.04. Boot Menu Is Split And Flashes On Bootup

Hi Guys, I installed a dual boot config. on a 160 gb hdd. The first choice in grub menu is Linux Lite (latest distro) and the second boot choice is Mint 17.1 Rebecca. I'm encountering a situation that when I boot into LL the system boots OK. Then when I try a restart and boot into Mint it seems to be doing OK until the end of the boot process at which time the screen flashes the Mint logo and then goes dark-then flashes then goes dark every second or so-endlessly. After a while I'm sometimes able to get Mint to finish booting by hitting the esc key. Any ideas how to make this screen flashing situation stop and do a normal boot?

Update: Solved the problem by changing the resolution settings to coincide with those of LL....flashing stopped!

LL and Mint IMHO are two of the best distros for a Newbie to "get their feet wet." - I know, I am that Newbie.

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?

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

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 installed slacko puppy on an old laptop. works great from the usb but will not boot from the hd. I tried the grub5dos bootloader config but got an error at the end that said
/usr/sbin/grub4dosconfig
version 1.9.1

Writing... /mnt/sda1/menu.lst
/usr/sbin/grub4dosconfig: line 1479: echo: write error: No space left on device
Failed to make 'menu.lst'.

Is their an easy to understand tutorial for this. I am not very tech savvy, so a guide for idiots would help.

hello,
I have a CentOS system and I want to prevent the boot messages from appearing during bootup. I have added the quiet option in grub.conf file which hides the boot messages, but after pressing the esc key or the arrows it shows up again.

Is it possible to hide it permanently?

Or not show the boot logs when the basic(esc or arrow) keys are pressed but assign a different set of key combos which when pressed, then only the boot messages should be visible.

Thankyou

On my partner's duel boot computer (Windows 7 & Linux Mint 17.1) after an update and grub upgrade the time the choices menu stays on screen is only a few seconds.

How do I extend that time from a few seconds to about 15 seconds that will give her enough time to choose her OS of choice?

Thanks,

gael

Booting to CentOS Linux problem. I have an HP desktop PC with an AMD CPU and win8.1 installed on it with UEFI as the boot process. The CentOS7 DVD indicates that I have installed the CentOS successfully. When I boot the PC it does take me to a menu offering CentOS and Win8. Win 8 will boot correctly. However, when I try to boot to CentOS I get a screen that says “Kernel not found”. The boot loading process continues until it ultimately brings up a terminal login screen. When I try to login with my password and usr name it tells me that they are wrong. I suspect the Kernel not found is the real problem but I can't get into the CentOS program to see if GRUB or any of the other programs are missing or defective. So far I have not disabled the UEFI since I didn't think I needed to. Any suggestions?

Hi all. I'm trying to set up a netbook with Ubuntu for my computer-challenged Mother. I downloaded the image file to the download section of the new netbook, created a USB stick to boot from and then restarted the computer, pressing F2 in order to change the boot order. Using the "+" key I was able to put [Removable Dev.] on top: "1st Boot Device", but, and here's the thing, it is disabled: "A devince enclosed in the parenthesis has been disab led in the corresponding type menu." I do not understand this, nor do I know what to do. Help please....
