Ubuntu Installation :: Use Grub2 To Have Live Usb That Retains Changes?
May 22, 2010
I have used grub2 to be able to boot multiple iso files on a flash drive as per this thread:
http://ubuntuforums.org/showthread.php?t=1484582
Is there any way to add a persistent installation of 10.04 to this flash drive, similar to what the startup disc creator application can do? I'd like to be able to have the clean installation and the persistent installation plus the other tools that I have on the flash drive. It's an 8 gb drive so there is ample room.

i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.
sudo fdisk -l
Disk /dev/sda: 320.1 GB, 320072933376 bytes

drive is as follows:
NTFS Partition (Storage)
NTFS Partition (Win7)
Ubuntu
I am trying to put GRUB2 on the Ubuntu partition, but it will only let me pick the first two. If I pick the Ubuntu partition in the last dialog bix, it is listed as /dev/sda-1 I also have no idea why is says "-1", because the first two are fine at 1 and 2 respectively.

I have been frustrated attempting to get Grub2 to boot a Debian Live system from hard disk. Have set aside a 4gb partition /dev/sda1 to contain the Debian Live and some other recovery tools. I actually have them all working from a 4gb USB stick successfully, but getting it to work on my HDD has proved challenging. On USB, I have PartedMagic, Gparted, Grml, and of course my standard 6.01 Squeeze. I have also managed to get the Debian Live booting from that USB stick. Very slick.
However, I can NOT get Debian Live to boot from my HDD; altho all of the others above boot fine. Have tried it two ways - one using an iSO image, which is how it is done on my USB stick. The other attempt is to copy the entire contents of the ISO to a directory.
Here are my directory structures:
debian_live_gnome_squeeze_i386- contains the following: debian-live-6.0.1-i386-gnome-desktop.iso initrd.gz initrd.img vmlinuz which is how it is laid out on my USB stick debian_live - contains the files from the ISO image The error I get is something like "panic unable to find live filesystem" My grub.cfg snippet for the two methods I have tried - the 2nd menuentry is similar to how it works on the USB stick.
menuentry "Debian 6.01 Live (on /dev/sda1)" {
insmod part_msdos
insmod ext2
set root=(hd0,msdos1)
[code]....
Probly don't really need to get it working since PartedMagic can do almost everything I need for recovery and I can use the USB for reinstall or whatever else.

I've been beating my head against this one for a few months.I have FF set to start show a blank page at startup - yet it remembers all my previous sessions instead. I've been through the about:config page to try and fix it, but it still won't start fresh after a shutdown.

I want to reinstall windows to its partition on my computer, but I want to be able to restore grub2 afterwards. I use a lot of custom scripts in the /etc/grub.d/ directory on my ubuntu partition, so how can I reinstall grub to the MBR using those specific scripts? Just running "sudo install-grub" or "sudo update-grub" doesn't work for me (I don't know the exact problems, but I can't reproduce it right now). If there's a way to install just the defaults (without overriding my custom scripts!) maybe I can just do that, but I'd really like to put the live cd, run a few commands, and install those custom scripts to the mbr and be on my way.

I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?

Is there a way to install grub2 from a linux live cd when linux isn't installed on any of the partitions? I'm setting up a multiboot partition for someone and I don't want to install linux anywhere on the computer since hard drive space is running short.

"In this tutorial you will prepare a USB flash drive to make it bootable. After you booted it it shows you a menu where you can choose which live system you want to boot. So you might be interested in this tutorial if: You want to have multiple live systems on one USB flash drive In the future you want to create a new bootable live system just by copying the ISO file onto the drive and edit the grub.cfg You don't want to or can't use Distro specific LiveUSB creator tools You prefer a cleaner solution than the most LiveUSB creator tools which create several folders and files at the device root You are feeling bored and want to see cool features of Grub2 If you have a Grub2 version with Lua support you even don't need to manually edit the grub.cfg when you add new or remove live systems." Remainder of information is found here: [URL] This was found in a closed Karmic Development forum - can this be validated and updated if needed for Lucid?

I've done a good few ubuntu installations for friends and colleagues and now my Dad wants in on the action. His PC is more than capable of running ubuntu 32 bit BUT I've hit a brick wall I've never come across before. I've burnt a CD image of the 10.04 iso from [URL] on my ubuntu box and for some reason, his PC just won't boot from it. If I select the option to manually select the boot source, all I see is the hardware monitor telling me things like CPU temperature. As for the Live USB - nothing whatsoever. Is it possible that I've managed to corrupt the iso file somehow?

Live CD: I dowloaded the ISO, burned it to CD, booted from this CD. It starts to load and I can see the purple background with the loading icons. Everything seems normal. But instead of ending up with the login screen, it ends up with a screen that says 'Please remove all bootup media and hit ENTER' or something like this. So I hit enter and then it shuts off my computer. That's it.
Live Stick: So I tried another option and created a stick with 'usb-creator.exe' that is on the CD. Then I start from that stick, but all I end up is a line of 'Syslinux bla bla copyright 20xx-2011'. That's it. Then it does nothing anymore. The cursor is blinking, but no prompt or whatsoever and keyboard input doesn't do anything.
Now something weird: When I insert Live CD and Live Stick at the same time and then boot my computer, then it boots into Ubuntu. Obviously it loads the first parts from CD and then the rest from stick. Because when I'm then in Ubuntu and try to format the stick, it says it can't do so, because there's system files from that stick in use.

I installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.
Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.

I have decided to dual boot again because I found a old hard drive laying around.
primary drive: sata 500 gb
ubuntu 10.4 64 bit installed with
boot
[code]...
secondary drive: 120 gb ide drive with xp installed. xp was installed first and wrote the mbr to sda1. I then installed ubuntu 10.4 and it overwrote mbr on sda with grub2. I have tried every combination of the 40_custom script for xp I have found here on the forums but to no avail. The 30_OS probe never seems to see it either. Grub 2 will not see xp. I have it in the menu from the custom_40 but it just reboots the system when I choose it. Any advice is greatly appreciated as I am ready to go back to legacy grub which only took 5 minutes to dual boot last time I did dual boot. I want to give grub2 a chance, since it supposed to be better, but I am getting frustrated.
Here is the output from the boot info script.
Code:
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #1 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb

I posted this about 3 weeks ago in the 'Desktop' forum and with no replies feel this may be a better area
I've got Karmic installed on my netbook which I understand uses Grub2 which is still a BETA version.
I still seem to have the original GRUB (legacy) within the file system, still have a menu.lst file but is appears to be showing the contents of grub.cfg at boot time.
What is happening at boot time, is GRUB Legacy handing over to GRUB2 at boot or is the an option for GRUB2 to hand over to Grub Legacy.

Here is my current setup. I have installed Windows 7 Home Premium 64-bit, Ubuntu 9.10 64-bit, and BackTrack 4 Final in that order. All operating systems are able to boot and all is working well. The only problem I'm faced with is really just an annoyance. Which is BackTrack is showing up with a "Ubuntu 8.10" entry name.
Now I did some research on this. I found out that BackTrack was based on the Ubuntu 8.10 OS so it makes sense why it would show up that way. I found several articles and topics explaining how to modify the GRUB programming files. I guess to change the entry name, but all of them don't seem fool proof to me nor the best way to go about doing things.
One thing I wasn't able to find info on is where GRUB2 actually gets these entry names from. My theory is if I can find out where GRUB gets this info from, I can simply log into the BackTrack partition and change where the "Ubuntu 8.10" entry is to "BackTrack 4" and then run the update-grub2 command within Ubuntu to update the entry names.

I installed Ubuntu 9.10 & grub2 on a Toshiba sattellite laptop last night:
- Win XP shows up in the Grub2 menu.
- When I boot Win XP, it says autock program not found, skipping autocheck, then Win XP stops booting.
- I did a little digging on the net, & found I have to unhide the NTFS partition for Win XP (hd0,1)
- Grub2 doesn't have an unhide command.
- I tried to run parttool, & got the "command not found".

I installed Fedora 12 on my second drive.
Xubuntu 9.10 is on my master drive, and I use it to install/update grub.
When I installed Fedora, I answered "NO" to installing a boot loader.
After install, I booted Xubuntu and ran update-grub, grub couldn't find (apparently) my new fedora install.
I've tried adding it to /etc/grub.d/40_custom, and when I list /boot/grub/grub.conf, it appears to have added Fedora to the bottom of the menu.
When I boot, it doesn't stop at the grub screen, indicating only one installation of linux.
Here are the pertinent file listings, can you see where I've gone wrong?
Code:
dav@dav-desktop:~$ cat /boot/grub/grub.cfg
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates

So I recently tried to install Ubuntu Lucid in the following configuration code...
The installation procedure went fine, and it said it had successfully installed GRUB2. But then, when I tried to boot up the fresh system, GRUB2 didn't even load!!
It's not giving me any GRUB errors, or giving me a 'grub recovery>' prompt, so I suspect that it really isn't even booting into GRUB.
I tried booting into the LiveCD, and installing grub to BOTH /dev/sda and /dev/sdb, but it still does not work, and I am at a loss.
Has anybody else had this problem?

Right I had to uninstall windows xp and install windows 7 to play more games! I use windows to play games and that is it. I have restored grub before and I even double checked with this guide: [URL]
I have two hard drives
sda - 320gb with windows
sdb - 100gb /home
-12 gb /
-480gb (NTFS) shared
However after reinstalling grub it still boots into windows! I will boot into windows properly then shut it down cos its coming up with windows was not shut down properly and if that doesn't work it has then been shutdown properly and I will install grub again.

I have Win 7 in my hard drive (sda) and I installed Ubuntu 10.04 in other hard disk (a usb disk), but when I try to boot my pc from the usb disk (sdb), the grub shell is displayed. No menu is displayed. When I boot Windows 7 from sda, it runs correctly. The problem it's when i wanna boot Ubuntu. I ran bootscript on the live CD and this is what I've obtained:
Code:
Boot Info Script 0.55 dated February 15th, 2010

GRUB2 won't boot. It hangs just after the 'Boot from CD' thing in my BIOS.I've had 1.97 working on my PC about 24 hours ago, but I decided to start afresh and go for Xubuntu 10.10.I'll post the PC specs in the morning, but in the meantime, does anyone know how to fix this?It's going to be a Xubuntu only system, and I've tried to repair the GRUB files via the Live CD and here.

i know i should look more through the forum, but i've been stuck on installing ubuntu on my computer for 3 days now, reinstalling, manual grub installing and so on, but no go. but i found a good thread on my still no fully functional ubuntu computer that explained very well for a complete linux noob how to install grub2 on ubuntu via the livecd. but since i was booting from the live cd meant that i couldn't bookmark it, and very little on this forum, as far as i can see, gets sticky, makes it very hard to find.
the basic problem is, i completly reinstalled ubuntu 10.10, and the bootloader (that i now know is named grub2) could not be installed. so i've found several guides, including the wiki, but it haven't really worked. now instead of explaining all of this over again, like all of you have probably done a million times, can you just post the most informative links here, so i can pick and choose,

So I have a really old (about 10 years) desktop PC manufactured by Packard Bell, and would like to get Lubuntu 10.10 running on it. I had previously burnt a CD with it, but boot time was incredibly slow on the machine and installation of Lubuntu crashed my system. As a result, I created a LiveUSB (as you do).
When I entered my CMOS, I discovered the BIOS on my machine isn't able to boot from USB, and I wasn't able to find a BIOS update for my AMIBIOS chip on the American Megatrends website. So I booted my GParted Live CD and created an ext4 partition at /dev/sda3, which I proceeded to install GRUB2 onto via the commands:
Code:
$ sudo su
# mkdir /mnt/grub/
# mount /dev/sda3 /mnt/grub/
# grub-isntall --no-floppy --root-directory=/mnt/grub /dev/sda
This, as planned, succeeded; I can now get into a GRUB2 prompt when my machine boots...! The only problem is, GRUB2 won't detect my USB...or any device other than my hard drive
So, is there any way I can get GRUB2 to find my USB?
P.S. The USB works fine on my laptop, which does support USB booting. I can also boot the USB on my laptop via its GRUB2 command line, using:
Code:
grub> set root='(hd1,1)'
grub> chainloader +1
grub> boot

Here is my problem. Grub2 outputs error: unknown filesystem. Then when i use "ls" command it outputs this:
(hd0), (hd0,4), (hd0,2), (hd1) and when i "ls (hd0,4)/ or any of them it says: error: no such disk
So, heres my story. I dual boot vista and ubuntu from my main 320GB hdd. Today i tried to fresh install 9.10 on a different external hdd. The 500GB hard drive already had two partitions, a 30GB Fat32 and the rest NTFS. both of these partitions had about 17GB used on them. I installed off a cd and i shrunk the NTFS to allow for more partitions. I made a 4gb swap as logical at the end then a primary ext4 / partition in front of it. The drives are Fat32 sdg0, ntfs sdg1, then an sdg3 (which im confused about and says is extension), and sdg4 (with linux) and sdg5 (swap). When finished with the partitions it asked me to select where to mount the ntfs and i said /windows. When i tried to boot up it did not recognize my external apparently because it was plugged in via firewire. I switched to usb and it booted but then i got the error message in grub. Also, when i switched from firewire to usb the drive changed from sdb to sdg. How do i fix this problem? Will reinstalling ubuntu fix this? Is there an easier way? I tried reinstalling grub but it did not work.

I upgraded yesterday ubuntu 9.10 to 2.6.31-19 kernel. After reboot, I get stack to GRUB black screen. No possibilities.
My set-up is triple boot 9.04, 9.10 and winxp. The MBR is handled by win boot.ini with no problems. Each ubuntu partition has a grub installed in it.
9.04 is on sda5 with grub installed on it ext3
9.10 is on sda9 with grub2 installed on it ext4
I am able to boot into sda9, via grub of sda5 obviously passing the correct kernel parameters and UUID.
