I have installed centos 5.3 64bit on my machine using pendrive. installation completed successfully. but now i am not able to boot my system without pendrive. do i need to make change in /etc/grub.conf
View 4 RepliesNote: I am doing such setup for the first time so I don't know if there is a problem with given opensuse version or problem with what I am doing. System: openSUSE 11.4 RC1
Desired setup: entire system except /boot partition on hard disk, /boot partition on USB (pendrive). Aim -- making impossible to boot from hard disk, forcing boot from the USB (please, don't question my aim, I am just trivializing the issue here to shorten the description).
Setup: I set /home and / partitions on hard disk (/sda), /boot partition on USB (/sdb), I selected the options to Boot From Boot Partition as well as Boot From Master Boot Record. Finally I selected Boot Loader Options and selected Set active flag in Partition Table for Boot Partition. I installed the system.
What works:
a) without pendrive inserted I cannot start the system
b) with pendrive inserted GRUB menu shows up and system is ready to boot
The problem: after initial starting, there is long pause, and system switches to text mode with error:
Code:
drive "/dev/disk/by-id/id_of_my_pendrive" is not found Since the console worked, I logged in, and yes, actually there was not such disk found. But the disk (pendrive) was there -- the initial booting took place not from void, but from it. So why it is not present? Out of curiosity, I pulled it out, and plugged it in back, now it was visible in "dev/disk/. Question: what should I change/tweak for correct booting the system from pendrive? Or is a bug in 11.4 installer? I would like to setup everything as it should be done -- I mean within installer.
What I found so far: Booting encrypted system from USB stick - Gentoo Linux Wiki it is similar problem to mine, but only similar. I have other symptoms.

Environment: A 32-bit kernel RHEL5.3 system running on a virtual machine. The root(/) filesystem is on an LV.

I got the following output.
I am running the latest suse release downloaded directly from their website. I ran the installation after buring the dvd and everything seemed to be working fine. after the installation i ran updates and used it for a little bit. When i shut it down that night and went to restart it I got an error that stated the OS wasnt there. I then went through the installation and everything and it retained the information from the installation before (web history etc.) but for some reason every time I reboot or shut it down the system is not able to read the startup information from the hard drive and will not come on without me re installing it.

This occurred after I was using it and then everything suddenly froze up on me and I had to crash out Now this!

I am using a custom operating distribution that has all the necessary modules to support USB during installation.

View 3 Replies View RelatedI need to use a pendrive with the Slackware 13.0 and I've tried a lot of things I've found at the internet but unfortunately they didn't work. It's not possible to use graphical interface because some reasons. So the problem need to be solved by command line.
When I use "lsusb" command, I can see the pendrive.
However, when I try these:
I got the following message: "Module usb-ohci not found" and "Module usbcore not found"
How can I deal with these problem? Because I guess without these module loaded it's not possible to mount the pendrive. Is it right?
Can you install Ubuntu onto a USB PenDrive and then boot it on a PS2?.
View 1 Replies View RelatedI have Slax on a pendrive (though I have tried other distros such as puppy, DSL and even Ubuntu 9.10 to no prevail either)I want to boot my dc7100 sff with it but it doesn't work. If I set my bios to boot usb first it goes straight to the OS on hard drive. If I configure for usb only I get the "Non system disk or disk error replace then strike any key" message. I installed slax to my pendrive using this method.[URL]..I am trying to use a PNY Attache 2gb but I have also tried a 256mb Kingston data traveler. When I try to use the same pendrive with my compaq c700 laptop it boots fine and runs great. Does anyone know why my DC7100 will not boot Slax from the usb?
View 1 Replies View RelatedI have tried googling this thing but returns didn't fit my needed answers while I have very limited time staying on-line, so I try to solicit help here from those who have gone this way before.
My Need:
1. I need to boot and run Slackware 12.2 from an 8gig USB pendrive. <Regardless from where I install them: I can install and prefer to isntall it from a DVD/cdrom drive. But booting my Slackware DVD installer cannot see the USB pendrive which fdisk -l returns as 'sdb1-ext2, sdb2-ext2 and sdb3-swap' after falling into the console mode.>
2. I partition my usb-stick into 1.2Gig to mount as / then 5Gig to mount as /home and about 200+Mbs for swap. Things I have tried--
a) I have run Ubuntu 8 on a pendrive by a very simple way of doing it. There are links for that. But I don't like Ubuntu where it uses vfat on a casper drive, and also I cannot control the system the way I used to in Slackware. I deleted it.
b) I tried booting my Slackware 12.2 DVD installer but there is no way to find my usb drive when preparation phase came. I need a little help. I have lesser time now for tinkering things, being busy in my job.
What would I do to attain my objective quicker than being a scientist-experimenting-things? Is there a link for a fitting solution so that I can go and read from there?
I created two debian bootable pendrive with the newest and basic commands: CP debian.iso and SYNC. When I tried to restoring the pendrive GPARTED sees only few space and is unable to perform any operation on the hidden partition as well in Windows 7.
CFDISK is able to see the partitions but is unable to write anything, just deleting. After deleted any partion GPARTED enconters a wrong block size so is unable to perform any changes.
Thus the only way I found to restoring the pendrive is delete the partion with CFDISK and then formatting the pendrive in Windows, where did I do wrong?
I was building LFS on a pendrive this morning when it crashed in the middle of making gcc. I rebooted without my pendrive and I never got into the desktop. Instead, I get a visually pleasing terminal telling me that it couldn't find and that the only way to reboot would be to press CTRL+D. I'm then given a command line and that's that.
Rebooting with the key inside works perfectly.
I reformatted my key and now there's nothing on it. I feel like somewhere somehow I added an entry to the boot process of my system and now I have to remove it. Never dealt with something like this before
Fstab:
/dev/disk/by-id/ata-WDC_WD2500AAJS-60Z0A0_WD-WCAV2M336077-part1 swap swap defaults 0 0

I have dual boot (wubi) Windows XP. It was working smooth until I upgrade ubuntu 9.10. At the boot screen I choose Ubuntu, then it ask me wich version, then it freeze. I tried the recovery version, but then it ask me for a user ID login and password. At this point I'm able to enter the user , but it don't type anything on the password and keep asking me to enter the user id and password again, and again.

View 8 Replies View RelatedI am new Linux, but have already installed a new HDD in my PC and successfully installed Fedora 14. Unfortunately, I am unable to configure my system for dual boot and my PC always boots right up into Windows Vista which is the original OS on my original HDD. I have searched the web, but only find examples of splitting partitions and dual booting into different versions of Windows. I apologize for the simple question, but I am certain that someone in here can point me in the right direction. My intention is to migrate to Linux entirely, but want to learn Linux before completing a full migration.
