Ubuntu Installation :: 10.4 Won't Boot In Presence Of Gentoo Drive
Nov 10, 2010
I've taken the plunge and embarked on my very first install/congifuration of Ubuntu. I've successfully installed 10.04 from the LiveCD onto a brand-new 500 GB hard drive. It boots fine. At least, it did until I reconnected another hard drive that contains a Gentoo system. (I had unplugged the Gentoo drive during the installation so as not risk mucking it up).In the presence of the Gentoo drive, the Ubuntu system starts to boot, but then fails with an a error that it's unable to mount /var.Investigation (df -k) indicates that it's mounted one of the parititions on the Gentoo drive. If I unplug the Gentoo hard drive, the Ubuntu system agains boots properly.
I have no idea why the 10.04 system even sees the other drive, much less mounts one of its partitions.My intent, once migrating to Ubuntu, was to copy needed user files and data from the old Gentoo system, then repartition the drive and use it for additional Ubuntu storage. Seems I can't get there from here.Is there some feature in Ubuntu that causes it to go looking for any other drives accessible on a system and then go about mounting random partitions?

Win-7 Ubuntu Dual Boot, Drive Presence Issue I recently built up a new computer and set it up for dual-boot with Win7 and Ubuntu. Initially I had some issues with the boot management but I discovered that GRUB works well and Paragon's Partition Manager does not. I reloaded Ubuntu using GRUB and got the system working exactly as I would like it to. Several weeks later I volunteered to assist my brother-in-law's family with getting their Unbutu system working properly with a new Brother MFC295CN printer. I brought the printer home so that I could work with it on my system.
I did get the printer to work correctly but in the process I had to reload Ubuntu because I made a few mistakes on my way to success. When I reloaded Ubuntu, I accidentally loaded it onto my system's second drive, drive F. Before, I had Ubuntu in a partition on drive C. Ubuntu works from the F drive and GRUB allows me to boot either Win 7 or Ubuntu, as desired. I will note that the earlier version of Ubuntu on drive C has been removed although the partition is still there. GRUB shows entries for this second copy of Ubuntu along with Win 7 and the entry for the functioning Ubuntu OS.
Here's where I am getting into trouble. Initially, everything looked fine. Win 7 worked, Ubuntu worked. Then, after a reboot to Win7, I noticed that my F drive was missing. I searched all around the system controls, tried loading new hardware, etc, etc, but the drive did not show up anywhere. Rebooting into Ubuntu showed that the drive was in fact still there and all the date in the large data partition was still there. Using Ubuntu's partition manager I discovered that the data partition was not enabled. I enabled the partition and rebooted back into Win7. No go.
The F drive was not present. My next step was to try Paragon's Partition Manager software, which I have a paid-for copy of. It would not see the F drive either. Using the Paragon recovery disk I had made earlier with the Paragon software, I restarted the system. The recovery software saw both drives correctly and the partitions were set up correctly. I ran the boot corrector software but I did not mess around too much as earlier experience had indicated that some of the Paragon features do not work well with Ubuntu. I shut down and rebooted into Win7. Success! The F drive was there.
But later, when I restarted the system the F drive was gone again. I tried a few things then rebooted using the recovery disk again. As before, on the next restart the F drive was present. I didn't take the time to reboot the system twenty times, but it seems apparent that something in the boot records is preventing Win7 from seeing the F drive correctly unless I boot from the Paragon recovery disk and then boot Win7.
No knowing a lot about what goes into a boot record and how either GRUB or boot.ini manage things, I am at a loss as to why I'm seeing this inconsistency with the F drive. A probable solution would be to remove both the second (old Ubuntu) partition on the C drive and the Ubuntu partion on the F drive and reload Unbutu all over. This would put me back to where I was in the beginning. However, this seems a bit inelegant as all the other attributes of the system are working well, is there a better way to address the problem?

Increasingly over time, i.e., days I experience that the keyboard (and mouse) is not recognized when booting.Now it's every time I boot. However, there is a fix. If I plug out, and immedeatly plug in again the keyboard connector everything is fine, except that keyboard short cuts not always work depending on application. In the mouse case the right mouse button doesn't respond either. Besides these effects the system, openSuSE 11.3, boots fine. It's a hazzle everytime to plug in and out again. I'm opting for another fix. Nothing suspicious in /var/log/messages. I've tried to see if there is a particular led light sequence on "num lock", "Caps lock", "Scroll lock" that I can get som info from, but I haven't been successful.Anyone got a suggestion to what might be the cause of this behavior?
Keyboard is kwd-205
Mouse is Microsoft wheel optical mouse

I have just had my Ubuntu 10.04.2 Luci installed under my Windows OS. Things seem to be fine until I find out next that my copy of Ubuntu does not detect the presence of the cdROM which installed the software itself on my desktop machine.
I have tried searching high and low for clue in this forum, tried all the recommended tricks to find out at last that there is no cdROM listed under my DISK UTILITY and when I input the following comman,
sudo lshw -class disk -class storage I only happened to see my hard drive and some USD drives being listed.
Also, Brasero Disc Burner does not detect the presence of a cd/ DVD rom devices.

I bought a Western Digital 1TB external hard drive to use with a Gentoo build. It connected beautifully, mounted visibly but despite being mounted read/write any attempt to write to it produced the error "read-only file system". I chased a number of red herrings before I found that the drive comes with an NTFS filesystem and NTFS support in my kernel was set to read-only, which I think was a default setting. Simple fix was to install a different file system - as it was a new drive there was no old data to lose.

I really want Python 2.6, which is not part of the standard Hardy packages. I just tried installing the Python 2.6 Linux distro direct from python.org. While I didn't see any error messages during the installation, I'm still defaulting to Python 2.5, and 2.6 installed to a different folder than 2.5.
A secondary wish: I would also like GROMACS 4.0 instead of 3.3. Again, Karmic has it as standard, Hardy doesn't.
I'm running dual hard drives in a software RAID1 configuration. My system is Linux only, so I have no Windoze compatibility issues to worry about.
Still, I've gathered that upgrading in the presence of RAID is different, and more problematic, than a standard upgrade.

I've partially installed Gentoo to a separate (RAID0) partition and would like to boot it from my Ubuntu 10.04 Grub installation. I have a /boot on RAID1 (mirror) and Ubuntu root on RAID1 (stripe set.) I have added what I could figure out to
Code:
hbarta@olive:~$ cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 $0
[code]....
And it starts to boot the Gentoo kernel. (That fails when it cannot find the root partition, but I think that is past the point where grub has done it's work.) what I have wrong in the Gentoo menuentry that causes it not to show up?

I am using Gentoo Linux and for a while now, the root file system is mounted read-only on booting. For obvious reasons, this is quite annoying as most services do not start up correctly (I do not use a separate file system for /var). After the system is up, I have to log in, remount the root file system read-write, fix /etc/mtab, mount all other file systems in from /etc/fstab and then start up all the missing daemons. I know that there are ways to make a system run properly with a read-only file system, but I would rather restore the old behaviour of a writable root file system.
The strange thing is that after running mount / -o remount,rw, the file system is mounted in writable mode without any errors. I suspected some problem with fsck, but now I have disabled automatic file system checks on the partition (tune2fs -c0 -i0).When I run dmesg, only these lines mention the partition at all, although I am not sure if not something gets lost because /var/log is not writable:
EXT3-fs (sda5): mounted filesystem with writeback data mode</code>
EXT3-fs (sda5): using internal journal
The line in /etc/fstab looks like this:

I'm just trying to migrate to Ubuntu 10 Beta from Gentoo. One option in the installer intrigued me. It said something like (from memory) "Use password to log in and decrypt my home directory".
What happens behind the scenes when I choose this? (How) can I enable this later on? (I didn't activate it because I wanted to migrate my Gentoo user's home as painless as possible.)

I'm having trouble getting GRUB2 to pick it up in the boot menu. to clarify: Does every OS need a copy of grub? My impression was that you have one copy, and it takes care of all the OSes you have. I got to the point in my Gentoo install where it asked me to install grub, but I didn't want to mess up my boot record or anything (which there is the potential for as I'm in unfamiliar territory). I switched over to ubuntu and tried

Back in Febuary, my wife bought a Toshiba Satilite from Wal-Mart and a few days ago the hard drive got toasted. So now I'm using an 8gig usb drive as the boot drive. I also have 2 other flash drives for downloads and such but overall I am very pleased.
I'm running 11.04 32 bit and was wandering if 64 bit made a difference. I've got 4 gigs of ddr3. It's slow to boot, but once it's running, it's faster then Windows 7. Very nice.
Is there anything I should chage, use, since I'm running it off a flash drive??
I have 3 seperat drives, 2 x 16 gigs and an 8 gig, and was wandering which one would be best for booting off of? What do I look for??
Here's what I got:
00:00.0 Host bridge: Advanced Micro Devices [AMD] RS880 Host Bridge
00:01.0 PCI bridge: Toshiba America Info Systems Device 9602
00:06.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 2)

I would like to install wxpython2.8 for python2.5, which I installed as an alternative version in the presence of the standard python2.6 using xubuntu 10.04 lucid lynx (see the end of this thread for how I did it).how would I do this without the installation going for the standard 2.6 version? I found some notes to that on the web:

I tried those, but somehow my wxpython installation got borked and would not do anything afterwards.

I am working on a light version of linux for no particular reason other than to see how small I could make it. I was wondering if INIT was necessary, or if I could perform all of the INIT-related tasks (fsck, unmounting, etc) by hand/bash scripts?
I do not need multi-user functionality (Or much of anything for that matter). I started off with a Gentoo base 2.0.2 Install with kernel 2.6.38.

I recently put together a computer with scrap parts that I have. It had no operating system on it at all. I downloaded Ubuntu on a different computer and burned it to a CD (I also verified the hash). I put the disk in and followed the instructions. Then when it wanted me to take the disc out and reboot I did so and clicked ok and it rebooted. I changed the boot order so that 0-HDD was first, and it said that the disk failed and wanted me to put in the system cd. Anybody have any solutions?

I have an Acer Aspire One ZG5 netbook. I have Windows XP home installed. I downloaded Ubuntu 10.04 netbook edition and put it on USB drive by Unetbootin. I booted from usb and it worked perfectly. I then installed Ubuntu to my hard drive from the live desktop and nothing went wrong. Perfect so far. Next, i shut down my netbook and took the usb drive out. I booted my netbook and it started loading Windows XP, didn't ask me if i want to use Ubuntu. I shut down the computer and pressed F5 while booting. It asked me what i want to do. I selected 'go back to OS selection' and i could only choose Windows XP from there. It was the only thing i could choose.

I have been looking around and cant really find a guide on how to do this, I have found guides on how-to put a live CD on a usb flash drive, but this isnt want i want to doI want to use a high-end USB flash drive as a sort of SSD to put my boot partition on, I think if i do this it will decrease my boot time significantly. If it works i am going to take the back case off of my laptop and install the guts of the flash drive inside my laptop, i think the mod would be cool, i just dont know how to do it on the software side

I've tried to boot my Ubuntu 10.04 from my disc drive, and installing it in Windows like an app, but every time I do my screen looks like it went bad. The top two inches are the way it should be but the rest is white, and I can't see anything. Is there some setting on my comp I need to adjust or did I just get a bad disc? The disc doesn't have a scratch on it and I've cleaned twice now.

I can boot and run the live CD "ubuntu-10.04.1-desktop-amd64." Verified checksum and is ok
When I install it via CD or after running in CD mode and installing from the desktop the system will not boot. 250gig SATA drive.I can't for the life of me get it to boot after installation. It keeps dropping into 'initramfs' I even tried installing "ubuntu-10.04.1-server-amd64" and get the same result.Is it something to do with the SATA drive?

After many failed attempts, I finally got Ubuntu on my Flash Drive (16gb). This was completed by downloading Ubuntu Desktop Edition (ubuntu.com), and using The Universal USB Installer to put the .iso on my Flash Drive.
When I try to boot my PC from the flash drive, I get a black screen saying...

I am trying to a friend setup his computer to dual boot Windows and Ubuntu. While the CD drive works (and can burn cds, rip cds, play cds, etc with no noticible impairment of function), it is unresponsive before the Operating System is loaded. What I mean is that when we put in a bootable cd (we've tried Ubuntu, Windows 7, Puppy Linux, gparted, Windows Recovery Disk) and go through the boot menu right after the computer manufacturer screen (HP), and select CD-Rom Drive, the screen goes black with the exception of a blinking white cursor. The computer will boot from the hard drive, and we managed to boot and install Ubuntu from a flash drive just fine.
Is there any reason why a CD drive might do this? It once, years ago, had a large amount of soda spilled in it, but I would imagine if anything was broken hardware-wise, the drive just wouldn't work at all. I don't know that much about hardware (or anything, really), but the only thing I could think of is that it could have something to do with an OS loading a more complete set of drivers than the BIOS.

I've made myself a multiboot usb drive and looking to add ubuntu to it. I've created a live system and its respective casper drive, made the changes I want to it and now looking to make the whole system boot to ram including the casper drive so I can use the same usb drive in multiple machines instead of having to have multiple usb pens.
I've added the toram option in the txt.cfg file but only the operating system (filesystem.squashfs) goes into ram so when I take the usb out, the files on the casper drive are lost.
Could you tell me either how to boot the casper drive to ram or how to combine or merge the filesystem.squash and the casper-rw drive.

I have a HP PC that I have installed a PCI SATA controller in. The PC doesn't support booting from the card.... So here is what I would like to do. (btw..I'm a seasoned noob on Linux.) I would like to be able to boot ubuntu 10.10 from a usb pin drive 2Gb to a point where the kernal can recognize the SATA drive then start the OS from the SATA HDD.
I can see and access the drive if I boot to a live CD but when I install it won't boot because the PC's bios does not see the PCI card. This has to be possible but my Google foo isn't strong enough to find out how. Would a simple GRUB install on the pen drive work?
