Ubuntu :: Drive Designation Changes Every Boot?
Oct 13, 2010
I have a line in fstab to auto mount a drive partitian
/dev/sdb1 /media/Data ext4 defaults 0 2
This worked fine until I upgraded to 10.10.
Now every boot I get the following message on the purple boot splash screen;
/media/Data is not ready yet or not present
S to Skip M manual etc
When I looked at gparted the drive had changed from sdb to sdf. I changed fstab and then ran sudo mount -a I then access /media/Data as expected, that is until I reboot then I get the same message and find that the drive has swapped to sdb again.
This happens every boot, If it was sdb on the last boot it becomes sdf on this boot and vice-versa.
Unbuntu 10.10 upgraded from 10.04 (64 bit)

I have only been using Ubuntu since shortly after Lucid was released. I am a new convert and use it to run a back-up device / media server I have a total of 5 hard drives in the device. I have the Lucid system files written to /dev/sde. I am running a Raid 1 array with mdadm on /dev/sdc and /dev/sdd. I have been prepping to run a second raid 1 array with /dev/sdb and /dev/sda with the ext4 file system. I formatted /dev/sda to have a full partition of /dev/ sda1. I then went to do the same to /dev/sdb and the drive was missing from both gparted and the native disk utility. My array with sdc and sdd is still running with both drives working fine.I swapped the sata cable from sda and sdb with no change. The system will not recognize sdb no matter what I do but it does skip /dev/sdb in boot up which tells me it does see it.I have provide the output of the commands df, fdisk -l, and cat /proc/mdstat.

I have a headless 8.04 server with 2 USB drives attached. I'm trying to move everything off the 1.5TB drive onto a few 300GB drives (so I can then use LVM on the 1.5TB drive and move everything back onto LVs.)I check the drives using 'fdisk -l'. They show up as sdc1 and sdd1. I mount them and start a cp operation.When I run fdisk again, the drives are no longer sdc1 and sdd1. Now they are sde1 and sdf1 (and of course, they are no longer mounted.
What could be causing this and how do I fix it?I need to fix this ASAP because the 1.5 TB drive seems to be going bad. Every few seconds I hear a big "click" as though the head arms are smacking against a stop. (This is the 2nd brand new 1.5TB drive that has started doing this!)

Computer is Gateway Netbook with Win7. I want to install Ubuntu ,but when I go to the next window after the keyboard section, I cannot find the right combination for the partition designation. I click install on a 50gb partition I made for the install. The page asks for mount points and says no root file system is defined. I put in EXT2 and a / , page told me I should have a section for a swap file. what is the correct information for these boxes? I am installing Ubuntu to learn the linux sys and I certainly don't know inough about it to come up with these commands yet.

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 have minor problem with upgrading a hard drive. I am running an old pentium lll with two hard drives. On the first hard drive I have two partitions of around 90GB each. On the first partition is installed winXP and on the second partition I have Suse 10.3, both booted by grub and living happily side by side. My second hard drive (which is formatted for windows is only 4GB.
My problem arises when I try to replace the 4GB with a 80Gb hard drive. When I disconnect the 4GB drive the system fails to boot up and complains with error 21.

I have a USB drive on which I want to install Arch Linux (using the installer, not unetbootin or something similar, as I want the drive to be persistent.) The computer from which I want to boot this USB supports booting from a USB floppy, not a normal drive. Is there any way for me to make a USB floppy on another drive and use that to boot the normal USB drive?

I am building a 10.04.1LTS server. I am putting the /root filesystem into a Software RAID1 partition. I want to keeo my /boot partition outside of RAID.Is there a way to have a boot partition on both sda and sdb so if one drive fails the second boot partition will work away - or should this be kept in with RAID also.

I have a Toshiba laptop with BIOS that will not recognize USB as a boot medium (I have purchased two USB 'thumb' drives with Distro's that do boot but the BIOS see them as HDD devices!)I did manage to install and boot a distro from the USB HD but ended up with the USB drive having to be connected' to select any of the OS partions, to boot anything.I do realize that somehow, when installing the new distro on the USB drive, I changed the GRUB configuration to be on the USB drive which obviously I did not want, so can

i have downgraded from Ubuntu 10.10 to Ubuntu 10.04. I've had some bumps along the way and finally was able to install 10.04 successfully. Right now, my computer will not boot from the HDD and will only boot from the USB drive that the LiveCD is on. When I reorganize to set HDD as primary boot, i get:id-laptop login:d-laptop password:and I can put that in but then it just gives me a command line that ends with ~$ i believe. How do I get it to boot from the HDD instead of from the USB without running into this problem?
If I resequence the boot to HDD as number two, it will juts go into the LiveCD mode. Am I supposed to reinstall 10.04 again? I know 10.04 was successfully installed because it said it was and it needed to restart so i hit the restart button. It also had my old desktop picture there and all my files AND i checked the system info before restarting (it confirmed that lucid lynx was running).

Dual Booting my laptop and unable to change the Boot Records on the drive. Not because I dont know how, but my primary OS will fail to boot(win7).
I have drive partitioned as follows...
sda1 = Win7 system (default install)
sda2 = Win7 Main (default install)
sda3 = swap
sda4 = Extension (I think thats what its called)
sda5 = / (ext4)
What I need is a boot cd or perferably Grub installed on a 256MB Thumb drive with the options to load the installed system from sda5.

I have a Dell laptop with Windows XP installed, and for various reasons (Help: I borked my WindowsXP boot when installing OpenSUSE 11.3) I can not install a GRUB boot loader to the first hard drive (hd0).
I currently have a second hard drive in this laptop with a perfectly working OpenSUSE 11.3 instance, but no way to boot into it. I remember back in ancient times, a common option with Linux distros was to create a boot floppy to boot into Linux rather than installing GRUB or LILO to MBR. Since this laptop doesn't have a floppy drive I'd like to do the same thing with a USB stick. Is there any way to install GRUB (or something similar) to a USB stick? What I am not asking here is whether I can put a full, bootable Linux instance on a USB drive - I only want a boot loader on USB that launches to the appropriate mount point on (hd1).

The Ubuntu installer think my /boot partition is (hd0,0). This is what it writes into grub menu.lst. My computer won't boot after install completes. The Ubuntu live CD shows this boot partition is (hd4,0) (sde1). But that doesn't work and after editing grub menu.lst to (hd4,0), the computer still won't boot. Some searching at the grub command line show the correct value is actually (hd1,0).

I installed Ubuntu 10.04 on a HP Mini 5102 using a bootable USB drive, but if I try to boot the machine without this USB, an error appears saying: Non-System Disk or Disk ErrorWhen I insert the USB, everything works fine. I check the USB flags using GParted, and it has the bootable flag set. On the other hand, the hard drive in the computer has no flags set.

installed Ubuntu on a laptop a few releases ago from a LiveCD with no problems.Recently, I built a desktop with the intention of putting 10.10 on it, but I cannot get it to boot. It seems to be a problem with the 2TB drive I put in being two large. I can run the installer just fine, but when it asks me to restart, the OS never boots up. Here is some discussion that I found on the topic:[URL]

I have Window XP on my hard drive and now I can't get it to boot for some reason? I think it might have something to do with the MBR. I removed the drive when I was trying to make a liveCD USB boot drive . Do you think grub took it off or something. Not sure if this is something I can fix in the terminal or not

I am trying to use a Sandisk 2 GB USB flash drive to boot this system but the system is ignoring the drive. The system boots fine from the CD or from the first hard disk.
Here are some details:
ASUS P6T SE mother board
Cooler Master HAF case
Ubuntu v 9.10 64 bit
Sandisk 2GB USB flash drive
I have plugged the flash drive into a convenient front panel USB connector, right next to where the floppy drive is plugged in. I used the USB Startup Disk Creator to copy a disk file containing Ubuntu 9.04 Live CD onto the flash drive, then I used install-mbr on that drive. I can use the usual tools such as nautilis to examine the contents of the flash drive, and for fdisk -l I get:
Quote:
Disk /dev/sdh: 2000 MB, 2000682496 bytes
64 heads, 63 sectors/track, 969 cylinders
Units = cylinders of 4032 * 512 = 2064384 bytes
[code]...
which seems to say that the flash drive is bootable. I am suspecting that the problem is in the mother board and/or BIOS. The BIOS is set up to boot in the following order: CDROM, removable device, first hard disk. I thought that "removable device" included USB drives but the system seems to ignore that drive. There are lots of USB connectors in this system. There is a keyboard, a mouse , a loudspeaker set, a floppy drive, and the aforementioned USB flash drive plugged into various USB connectors on both the front and back sides of the cabinet.

I want to automatically mount an SSH server on boot. I am able to do this manually by running this script after I reboot
Code:
#!/bin/bash
clear
sshfs -o idmap=user user@server:/ /home/fro1269/sshmount
I have put the script in /etc/networking/if-up.d/
but it does not mount after the network is connected. This is on a laptop that connects via wifi. So my network connection does not start until a few seconds after the desktop loads. I am running 10.04.

I have a system with two drives, sda and sdb. Ubuntu 10.04 is installed on sda and Windows 7 is installed on sdb. I _can_ boot both Ubuntu and Windows if I change the boot order in the bios, however, when I try to boot the default Windows entry from the grub menu, the screen simply goes blank for a couple seconds and then I am once again presented with the grub menu. When I try to boot any of the "fixes" I found online I get, "error: invalid signature." Below is the default /boot/grub/grub.cfg along with 6 of the "fixes" I have found via google and ubuntuforums, and my dmesg.
Code:

# DO NOT EDIT THIS FILE

# It is automatically generated by /usr/sbin/grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub

I want to try installing from a USB drive. I can create a USB start up easy enough. The problem is when I go into my my laptops BIOS and boot order set up there is no option listed to select the USB in the boot order. The "closest" option is "Floppy Diskette" which of course I don't even have!
How to set the USB drive as the first boot option or might it not be possible on this machine?
