Ubuntu Installation :: Missing DVD ROM Drive When Empty During Boot
Jun 11, 2011
I am completely new to Ubuntu/Linux and am having trouble getting my DVD-ROM drive to work. I've tested a few things, and it seems that if there is a CD in it when I boot, then it works fine, but if there is nothing in it then Ubuntu won't list the device. The DVD-ROM is master on a PATA cable and the CD-RW is slave (yes I know it's getting old now...) Drives worked fine under Windows XP. I don't know very much about the boot process, but the following from kern.log seemed relevant: Booting with a CD:

I am trying to install ubuntu 9.10 on an system which already has XP installed. I had used Ubuntu earlier but when I installed XP ( in an attempt to dual boot) I seem to have lost the Ubuntu Installation. But the problem is GParted or the Ubuntu installer dont recognize the existing partitions but instead see it as an empty unallocated drive. I have a 120GB hard disk. Below is the extract after fdisk:
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x4fa8a60b
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x4fa8a60b .....
Also this is how the disk Utility in Ubuntu sees my system: ( See attachment)

I just bought a new HP desktop, and I want to install Debian on the hard drive. I ran the Windows program on the Debian CD to start the install.
I selected Manual drive setting, and resized the large C: partition to 50 GB. I want to install Debian in some of the free space, only their isn''t any free space! The 400+ GB I took out of the C: partition is labeled "unusable" instead of "free space."
If I double click the unusable space, I am just given the cylinder/head/sector numbers. How I can make that space usable?
I would boot my Gparted CD, but I don't know how to get to the BIOS. The boot screen goes right to Windows without showing me the key to get to the BIOS. I tried hitting DEL, but to no effect. Do you know what the HP computers use to interrupt the boot?

I have been using g4l to do cold backups of my OS partitions for a LONG time. I finally decided to configure a boot USB flash drive instead of a CD for this purpose. Using the EXCELLENT instructions on this page [URL] I configured a Lexar 1 GB Firefly drive and have used it for some time. When a newer version of g4l came out I decided to build another boot flash drive using a Verbatim 1GB drive. I followed the same instructions and...
The Verbatim flash drive will boot my Dell Studio XPS and my Dell Latitude 2100 netbook. It will NOT boot either of my Dell Dimension 4600s. The Dimension 4600s respond with a message "Missing operating system" when I try to boot from the Verbatim drive. The Firefly works on all machines and I configured Kingston 1GB and 2GB Data Travelers which also work on all machines.

I've managed to get a hold of a 160GB drive, which I hope to use as my system drive for a server that I'm setting up. This may be the tip of the iceberg (as it tends to be with me for some reason), but this is what's happening:
I got the drive, which has been used before but has been secure erased, and it's been sea tool-ed so is therefore as good as new. It shows up fine in the BIOS, and GParted discovers it straight away. I then split it into 3 partitions:
A ~10GB system partition - sdd1
A ~130GB storage partition - sdd2
A ~4GB swap partition - sdd3
GParted performs all actions straight away with no issues.
After partitioning, fdisk -l reports the following:
Code:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x2bd2c32a
[Code]....
I've then gone to install Ubuntu. I go through all the major steps, up to where it asks you where you want to install Ubuntu... at which point sdd just doesn't show up at all. It shows sda, sdb and sdc fine, but sdd is nowhere to be seen.
Two things strike me as odd (although I suppose understandable) - Firstly, every partition in sdd mounts fine, but is owned by root. Secondly, each partition has a folder called 'lost+found' with varying amounts of data. There's 662.3MB in the 10GB partition's lost+found folder, and 6.9GB in the 130GB's folder.

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 also tried to install virtual pc and get not boot disk found.

I have just installed ubuntu with a USB key, I have Vista installed in drive C: and I created a partition (L: ) and installed Linux root (/ ) in that one.When there was the screen where I could choose the boot loader i left the default option instead of choosing Windows Vista Loaderand now I can't boot Vista anymore.
In grub i see a windows vista option, but that option brings me to a recovery partition and not to the real operative system. I know that vista is not broken because when I used wubi I was able to boot from the vista bootloader without any problems, but I never could boot vista from grub because it brought me to that recovery partition.I can access all my files on the disk from ubuntu, but I would like to be able to restore the vista boot loader and use again windows when I need it.Is there a way to restore vista's boot loader? I tried to do automatic startup repair from the vista recovery cd but it says that no problem could be found.

Apologies if this has been asked before, which I'm sure it has from what I see googling around, but I cant understand this fully.
I have a piles of files in the .Trash-1000 folder on my flash drive that I want to delete. I can see them if I go in as root using the command line and entering "gksu nautilus" but it still wont allow me to delete them.

I've just installed Ubuntu desktop 10.10 (32 bit). No matter what programs I run, the CD-ROM (DVD-ROM) drive is checking for a new CD/DVD every 5 seconds or so (even if no applications are running). It is quite annoying because of its robotic noise. The drive is empty. How could this be turned off? Is the media manager misconfigured by default?

I'm trying to install OpenSUSE on an external usb drive but when I boot from USB, all I get is a message saying "Missing Operating System". I've tried different ways of partitioning the drive either by letting OpenSUSE do it automatically or doing it myself. It's just a basic partitioning scheme, with swap on one partition sdb2 and the rest on root sdb1 .
I made sure to have GRUB be installed on the root partition of sdb (usb drive) instead of in the MBR (I've installed Fedora and Ubuntu on usb drives this way).

I just upgraded to Natty 11.04 and am getting used to the Unity Launcher. I was trying to add a terminal to the launcher and I'm not sure what I did but now if I copy the icon from nautilus "/usr/share/applications" over to the launcher it creates a blank space like the icon is missing but if you scroll over it and right click you see Label Empty / Keep in Launcher.
The weird thing is that if I create a link to terminal in /usr/share/applications and drag the link over to the launcher it appears as it should.

I recently upgraded to Ubuntu 10.04 and everything was working fine. Last week I was away from home and when I returned, my wife told me that she cannot boot in Ubuntu. We have used dual boot for Windows Vista and Ubuntu. Now only Windows was working. So I created a LiveCD from Ubuntu website and tried to boot.
I can boot using LiveCD. Then I tried to install grub. I forgot exact commands I found online, but something to do with /dev/hda1) and now everything is messed up. It does not show boot menu (to select OS) at all. It only shows grub> window. I believe that the OS on the computer is alright, just the boot option is gone. I do not know how to get back the grub.
When booting from LiveCD,df /boot shows filesystem as aufs (no idea what it is). If I go through File browser, I can see the windows files and my Ubuntu installation. So I believe OS is okay, just not the boot loader.

Just installed Lucid on dual boot machine, Linux is OK but tried booting to Windows XP from grub2, missing hal.dll (this is apparently a common problem and I found many many posts on this topic). Boot.ini contents below:

Searching for solutions, looks like most appropriate solution is to load the Recovery Console from XP setup disk, delete boot.ini, restart the Recovery Console and run:

When I load the disk I can view my backup drive properly but when I try to view my working drive it shows it as being empty. I also noticed that I had a 1 mg unallocated partition at the beginning followed by my ubuntu partition.
I then ran gparted in terminal and it did show the partition as having my system on it but I am not able to perform any tasks. No moving or resizing.

I had a dual boot system(WinXP and Ubuntu). But something happened and I was not able to boot into my Ubuntu partition. It gave GRUB missing error. I tried reformatting the dedicated 40 GB ubuntu partition to NTFS and again try to reinstall ubuntu. But now, when I install ubuntu through boot time install, it shows that my whole hard disk is empty( but I have windows XP on whole hdd at the moment) and do not give any other option but to use whole hdd.
Alternatively when I try to install it inside windows, then after rebooting it shows, no root file system defined error and neither gives any option to do so also ( this method worked earlier o my PC). At the moment, It still shows ubuntu and windowsXP at OS choice menu at boot time but when booting in ubuntu, it shows GRUB missing. (I don't have any ubuntu installation on my hard disk at the moment).

I had installed Fedora 13 on an unused partition of my ATA hard-drive yesterday. The primary OS here was Windows Vista.
Anyway, everything was working fne for coupla hours after which I had to restart F13 for some reason. This is when all the trouble began ..
Fedora wouldn't boot cause of some "power issues" - there were none. Windows Vista wouldn't boot because "BootMGR was missing"
I figured if I removed Fedora using the live CD - format the partition, it would help. It didn't. Well, atleast the partition got formatted. I tried re-installing F13 from the live CD but it doesn't finish the process - saying a command, something to do with 'shutdown' is not valid.
I tried repairing Vista from the Installation DVD but it is unable to do so.
Right now, on rebooting the computing, I enter the 'grub' console. I tried using grub commands to boot "Windows" from the (hd0,0) partition like thus,
Code:
grub> rootnoverify (hd0,0)
grub> makeactive
grub> chainloader +1
grub> boot
But it still maintains that "BootMGR is missing" .

I used the update manager to update the kernel and whatever the other recommended updates were yesterday. I shut the computer down overnight and now when i try to boot into Ubuntu 9.10 i get a basic grub shell and when i try commands like "boot" it tells me there is no kernel loaded. I installed Ubuntu with Wubi so it is a dual boot system.
I've tried to access the Linux volume with a live OpenSuse 11 CD but there is no device to mount. It sees the entire hard-drive as if it hasn't been partitioned. I don't necessarily need to fix the installation. I just need to get my files back.

I have a Dell Dimension 2350 with an Intel 82845G Graphics controller that is connected to a 15" Craig flat screen television via VGA. It has absolutely no issue running at the television's peak of 1280x720 at 60 Hz with Windows XP. When I first discovered Ubuntu, I immediately tried to install it. After a tedious month of failed attempts, I resolved to doing what I opposed: using Wubi. I did not want to use Wubi because I wanted Ubuntu on a separate partition.
This is where my issue is. After installing Ubuntu 10.04 Lucid Lynx, I rebooted and started normally. I noticed that audio was present but all I saw was a blank "No Signal" screen on my television. I waited for over an hour, to no avail.computer was responsive. This was obvious when the computer released audio when a button was blindly pressed. I reinstalled after waiting even more, suspecting a failed install. I then used the failsafe graphics upon pressing escape after my third failed install. This worked, but it gave me an unsightly 640x480 resolution. I did my best to fix this, but it came to a dead halt with an error I could not fix: a CRTC error.
I then installed Ubuntu 9.10 Karmic Koala without an an issue. Everything was perfect except for the fact that I did not have the most updated Operating System even though it was free. I decided to to update 10.04 via Update Manager, thinking that all would go well. It did not. My mistake in updating brought me back to the drawing board.My official Ubuntu 10.04 Compact Disc arrived in the mail yesterday. When I hit "Install" I eventually end up at the same "No Signal" screen

just recently, while attempting to boot to windows 7, i happened to select the wrong boot option by mistake, that is the windows 7 recovery (something like that, cant remember it specifically, but the word 'recovery' is there). the option has been there eversince i installed ubuntu 11.04 on my system, of which i cant find the answer as to why it existed there. so once i selected it (which was by mistake), it took me into some recovery process which i abandoned as quickly. it restarted and the windows 7 option was no longer there. the windows 7 recovery option, however, is still there. How to get my windows 7 boot option back?

I just netinstalled Squeeze to a netbook with Windows7. The installation went well without any problem. Linux is also working OK. When I boot now, grub does not show Windows7. I took default settings during installation. I mean I did not do anything special. What should i do to fix it? Should I run osprober and grub-update?

I have read a number of threads relating to the bootmgr missing issue but I can't seem to apply the fixes to my specific situation, any assistance is most welcome; my details below. I have two HDDs
1 x IDE HDD running Fedora 12 which is allowing me to write this,
1 x SATA HDD which has win7 premium 64-bit, and up until the Fedora 12 instal, was the only OS.
Grub gives me two options for boot, they are: Fedora Other When I select 'Other' I get hte message :BOOTMGR MISSING My assumption is WIn7 located on my SATA HDD = Other what I might do to allow Win7 to boot.

I'm testing out 10.04 on one of my partitions, and I love it. I have been using it exclusively for a while now, I have not logged into Windows since! Really don't care about windows anymore!However, yesterday I went to boot into windows... and I noticed the option to choose it is missing from my list! Maybe I'm just not getting to the correct list? The list I get shows like 5 different modes and versions of Ubuntu and something called Windows Recovery (which does nothing), but that's it.
