General :: Create CD-ROM Boot Disk?

Jan 7, 2011

i have linux operating system CD. it is bootable. but i want to create a boot disk. now i can create boot disk on floppy. but i want to make CD as boot disk.

how to do that.

first i created .iso file like this mkbootdisk --iso --device myimage.iso 2.6.18-194.el5

it created iso named myimage.iso in / now how will i copy it to cd rom i am running cdrecord --scanbus

it is showing : this version is an nofficial version with DVD support. and therefore may have bugs that are not present in teh original. please send bug reports or support requests to http.... the author of cdrecord should not be bothered with problems in this version. cdrecord: invalid or incomplete multibyte or wide character. Cannot open SCSI driver.

cdrecord: For possible targets try 'cdrecord -scanbus'
cdrecord: for possible transport specifirs try 'cdrecord dev=help'.

i am inserting blank CD in the cdrom.

then i run cdrecord -v -eject speed=16 dev=ATA:1,0,0 myimage.iso

how will i come to know about dev and version information if cdrecord --scanbus is failing above.

i am having laptop. with rhel5 (2.6.18-194.el5)

Ubuntu :: Create Custom Boot Disk?

Feb 2, 2010

We have a project we are working on and wanted to know if it is possible using the ubuntu(or any linux) boot disk.

We need the disk to first wipe the hard disk in the notebook, then perform a hardware test(testing processor/hdd/ram/display) then it should reimage the machine and reboot from the HDD.

I am thinking of using grub4dos to boot(and timeout to the HDD)

and partition image to image the HDD... but i do not know any cli software for the others...

For note the disk has to be completely automated as we don't have the headcount to recheck every machine every few minutes.

Ubuntu Installation :: How To Create A USB Boot Disk

Apr 21, 2010

I have a Samsung N110 running Windows 7 and I would like to install Ubuntu Netbook remix which I downloaded from [URL] I want to install it on the netbook in lieu of Windows so am not looking for a Live CD/USB option. I have run usb-creator.exe on my XP machine but no matter what I do I can't get the "make startup disk" to un-grey. I have selected the CD which contains the iso I unpacked, and it detects my USB drive (I:) which is 4Gb I had exactly the same problem at work when trying this with the .iso I downloaded so it isn't specific to this machine.

General :: Can't Mount Usb Disk - It Just Create /dev/sg Device But No /dev/sd

Dec 23, 2010

I have a Corsair R60 ssd disk which is a disk with both sata and usb connectors. But the usb thing seems to be a bit non-standard, or maybe its just my fedora linux.When I insert the disk using a usb cabel to a running Fedora 14 linux system, a device called /dev/sg3 is added but that is all. No new /dev/sd* device is created so I can't mount the disk.

If I look at

cat /proc/scsi/sg/device_strs

I get

ATA Hitachi HTS54321 FB2O
Seagate Desktop 0130
Corsair CSSD-R60GB2

So the disk is there. (The last entry) but my linux will for some reason not see it as a usb hard disk. When I insert other usb disks they work fine. It is only this specific disk which causes problems. I have tried on 3 different computers with the same result.

A hint to the problem may be that if I add the disk to a windows system(With usb) the disk is called "A fixed disk" and not a portable disk as expected. The disk works fine with linux If i connect it with the sata cabel, but I would really like to have it working with usb too. (To mount it on computers without sata).

Added:I did try to mount /dev/sg3 but mount say that its not a block device. (File say Its a character special device).

Added output from dmesg:

[ 97.454073] usb 7-1: USB disconnect, address 2
[ 105.913055] hub 2-0:1.0: unable to enumerate USB device on port 3
[ 107.048054] usb 2-3: new high speed USB device using ehci_hcd and address 5
[ 107.162900] usb 2-3: New USB device found, idVendor=1b1c, idProduct=1ab8


I found an other guy with exactly the same problem [URL] so I think its beginning to look like a bug in the drives firmware or in the linux kernel.

Final update:Corsair have said that the disk design is broken and there does not seem to be any way to make it work.

General :: How To Create Disk Image Of Actual Data

Nov 15, 2010

Suppose I have a 80 GB hard disk (sda) with 4GB of contents. Using a dd to copy to a different disk

dd if=/dev/sda of=/dev/sdb
copies all the contents (including free space). So sdb also needs to be 80GB.

You will notice that in VMWare or VirtualBox disk images, it is possible to set the disk to use only the amount of space of actual data. So a 80GB virtualbox/vmware image with 4GB of contents will be 4GB.

Is it possible to do that with an actual hard disk (sda) image? I want to create an image of an actual hard disk, copy it to DVD and transport it (in mail) for restoration on another computer (having same hard disk).

General :: Boot From Disk With Both USB And SATA

Aug 17, 2010

I have a SSD Harddisk with both an usb and Sata connection, and I want to be able to boot both from usb and sata but I can't make it work. When the disk is connected with sata anything works fine but when I connect it with usb instead, Fedora seems to boot but then it gives me an "No root device found" error and just sleep forever. This happens even if I install fedora 13 while the disk is connected with usb. I am running Fedora Core 13. I changed my fstab to
/dev/sda2 / ext4 defaults 1 1

And the disk is still booting when connected to the sata controller. So far so good. But if I boot from the usb connection, it still give me the same "No root device found" message. Even more odd is it that if I boot my fedora core 13 dvd, and choose "rescue installed system" it can't detect the harddisk when connected to usb. And there is no /dev/sd* or anything similarly which could look like a blockdevice. Did redhat forget to include usb drivers in their rescue image for Fedora core? I just tried the disk on an other system, with exactly the same problems.

I have now added the LABEL=myroot line to fstab(I guess it have to be uppercase to work) and the harddisk still boot fine when using sata, but it still can't boot using usb. I begin to guess that redhat forgot some usb drivers In fedora Core 13, because the system can't see the harddisk when booting the dvd and entering rescue mode. blkid don't show any harddisks at all and there are no block devices in /dev/ which might be my usb disk. Is it possible to find the uuid of partitions if id add the usb harddisk to a windows computer, and more important: will this be the same uuid as linux will se.

General :: Got Error Message When Tried To Create LV For /boot?

Jul 28, 2011

While installing linux, i got error message when i tried to create LV for /boot... i checked with my friends n they told me that /boot should be a standard partition... why is that, i asked them but they had no good explanation for it... could someone please explain me why do we create standard partition for /boot, why can't i use LV??? also i heard that its good practice to create separate partitions (LV or standard) for /, /home, swap & other major directories instead of 1 partition for all these.

Hardware :: Fedora 11 RAID 1 - Disk Failure - Boot From The Single Working Disk?

Oct 16, 2009

my Fedora 11 system is not starting anylonger. It stops with the message:


VFS: Can't find ext4 filesystem on dev dm-0

The system told me since a while, that a lot of the sectors of one disk of the (software) RAID compound are failed already. So tried to disconnect each of the disks and start them separately. Unfortunaltly this is not working (for one its is not working at all, the other wents the same far as with both), when I tried to recover the system with the Fedora DVD, it said no distribution found. I am quite new and do not know so much about linux system, so i do not know what further information you could need. Maybe it can be important, that both disks are encryped (the system wents so far, that I can type in the password).

Debian Installation :: No Boot Disk Has Been Detected Or Disk Has Failed

Nov 3, 2015

I installed Debian on my PC with a Acer Stock motherboard (xc600) with amd64 and after the installation finished it told me to remove my installation media and reboot. After reboot I was returned this message ' ERROR: No boot disk has been detected or the disk has failed.'. I have verified with gparted using mint live OS that I have Debian installed on my system.

I got believes that this may have be caused by a broken grub or I need to configure something I don't know how in BIOS.

I will update the topic later..

My installation media was a USB 2.0 flashdrive with a Debian 8.2 Jessie Installer and 9 different Linux distros. I have installed Debian multiple times before on my laptop and never had this problem so I know how to go through the installation process and set the partitions.

I would use this boot during travel where I surely does not need these services and shorter bootup time is preferable. Permanent removal of such services is not an option because I could not miss them during normal daily work.

General :: Unable To Create Boot CD With Kickstart File

Mar 18, 2010

I'm unable to create a linux boot cd with a kickstart file. I have a working kickstart file and a working boot image (tested by booting using the network for the kickstart file), but I can't seem to put them both on the DVD.

Here are the steps I took
1. mount the *.iso file to /mnt/isosetups
2. Recursively copy all the files from /mnt/isosetups to /mnt/bootcd
3. removing /mnt/bootcd/isolinux/
4. running the mkisofx command (used -c to recreate
5. put the new image on a windows box and burned to a dvd using roxio

The result was that I could enter the red hat boot menu but the server couldn't find the boot image on the cd. I could go into more detail about what commands I entered, my environment, what I tested, etc.

Ubuntu Installation :: Disk Error On /boot With Dual Boot On Dual Disk

Dec 30, 2010

I have a (slightly complicated) dual/multi boot system.

I keep getting boot errors (when choosing ubuntu from the grub2 menu)

Serious errors were found while checking the disk drive for /boot

If I switch off and restart, ubuntu will then start without issue.

My setup is like this ....3 disks, one with 10.10 clean install - so Grub2, separate partitions for /, /boot and /home, one with windows 7, one with windows XP and 10.04 wubi (this is my old disk which I will trash once I'm happy with my upgrade to 10.10 & 7 on separate disks.

I installed 7 and 10.10 with ONLY their disks installed. After both were working, I added all disks and rejigged the grub2 menu (using update-grub and StartUp-Manager).

This problem only seems to occur if my previous boot was not 10.10 ( I will investigate this further). It's as if something (grub2 ?, the bios ?) is remembering part of the previous boot and not using the grub2 menu completely.
