General :: Connecting To Net With Rescue Cd?
Aug 18, 2010
I was ill a few days ago and in bed stumbling LOL cat pictures when I got hammered by a drive-by trojan. I'm sure I will have to do a complete install of windows and all my stuff, but I wanted to get the pc working to the point where I could move files off one drive to another.
So, I started trying out various linux based rescue cd's, Avira, BitDefender, F-Secure, and all off them will not connect to the internet. I have a att two wire modem set to bridge mode and a linksys router. I'm using this set up to send this message with off my laptop wired to the router. Also, from my laptop I can view the shared folder on the infected pc. So, to me it seems that it should work.
I did have to replace the onboard lan with a pci lan card, but I did turn off the onboard lan and the (cheap) lan card shows up on slot 1 using irq 10 during post.

I got my wife to try Linux, so we set her machine up to dual boot with Windows. After a few weeks, she decided not to use Linux, so we deleted the Linux partitions using Gparted on a USB drive and resized the NTFS partition, under the apparently mistaken impression that Grub would detect that there was now no other operating system. When we rebooted, we got error: no such partition, followed by a grub rescue prompt. I've never worked with Grub directly before, so I have no idea what to do at this point.

i have a server which i have no physical access to, all i can do is boot in rescue mode from a live debian CD and i want to know of a way to install CentOS from iso image or maybe NFS? on that server using this debian live CD.
since it's live CD i can't mount the iso image and boot from it cos after reboot nothing will be preserved. so the case in breif is, i am booted form debian live cd and i want to install CentOS on the machine from that system using iso image

I have dual boot with Ubuntu 9.10 and Windows 7. Today, after using Partition Wizard on Windows to resize its partition, I got the following message when reboot:
Code:
I dont actually know what to do, I've been reading some threads on the internet but nothing equal to my case, only people who installed Windows after Linux and lost GRUB. Do I just need a live CD to reinstall GRUB? Can somebody tell what to do?

I had Windows 7 and Ubuntu 10.1 installed in my intel i3 4gig DDR Sony Vaio E-series laptop. Both operating system were working fine. Only problem that I used to have was the sound didn't use to play when I boot through Ubuntu. Due to that, I formatted the corresponding drive from Windows in which there was Ubuntu installed. I used "diskmgmt.msc" to delete the partition and then format it. The format was successful and when I restarted my computer, this error was displayed:-
error: unknown filesystem
grub rescue >
Windows didn't load at all. I used to have multiple boot grub menu previously before formatting the partition but that didn't show up after formatting.I am unable to use any of the Operating System.

I am to reinstall the notebook of my father, that had Windows XP and Ubuntu on it. And I dont know anything on Ubuntu. My objective was to make a fresh install with XP only.So I was checking the partitions within Windows and found 7 or 8 of them which I could not understand: I asked to remove them, one by one, and got some error mesage on Windows. Now I understand these were probably used by Ubuntu.Now, when I restarted the PC,n I got:"error no such partition grub rescue"..I tried to boot from the CD - a windows XP setup CD, but I get blocked as well, because when I try formatting the drive during the installation CD it makes an error, or otherwise without formatting I also get an error.I guess the partitionning information of the hard drive is inconsistent, making everything fail.I dont know what to do.I am thinking to use a USB disk to reformat the HD, but I am not sure it will help.

I've got CentOS 6 installed and am wondering if it's necessary to have installation media in order to run 'linux rescue'. (I have to do some LVM resizing and would rather do it from rescue mode than in a running system.)
What I've read about booting into linux rescue is that it seems to be necessary to have installation media and boot into that. But I'm wondering if it's possible to do it some other way, like from the grub menu? But it doesn't seem to be possible to enter 'linux rescue' from the grub command line (which I got to by typing 'c' in grub menu screen) - typing 'linux rescue' at grub command line says 'command not found'.
Maybe there's another way to do this? Or some fancy way to have loaded a rescue image or something onto my disk so I don't need installation media. There's 2 reasons why I'd like to enter linux rescue without installation media, both because my computer is very old. 1) My computer can't boot from USB, and 2) My CD/DVD tray is very unstable and keeps popping out intermittently, so I'd need to hold the tray in place during the whole LVM process and it's a real pain, and I wouldn't want to risk data corruption if the process is interrupted by my CD/DVD tray popping out.
I'm hoping there's some way - it'd also be nice to know how to do this if some urgent situation arose where I needed to enter linux rescue mode but didn't have installation media handy and it'd take to long to retrieve or create new installation media.

I just installed ubuntu on my computer that already had windows 7 on it so I could dual boot them. After installing ubuntu and playing around on it a little I went back onto windows. I then restarted my computer and now it won't startup. I get an error that says unknown filetype grub rescue<. I don't know what to do to get back into windows or ubuntu.

Yesterday I installed the latest version of ubuntu to my computer that was already running windows 7. I had everything working fine until in windows I deleted a partition that had nothing in it.
After this I restarted but I can't get into either OS. I get an error that says Error: unknown filesystem grub rescue>
I think I need to fix something in grub. I have been booting off of a usb stick with linux on it in the mean time.

If I could I would change the boot order but I can't do that (I have a Dell Studio 1747). I try F2 to enter the BIOS set up, but I still end up with that error and never get to the setup. F12 doesn't work either (F12 is for the boot order) so I can't boot from the DVD with the Win7 installation DVD as the computer just freezes and I can't get past the Dell splash screen.
I have tried to remove the coin battery on the motherboard in an attempt to reset the BIOS but that didn't work either.
So...
F2 = error
F12 = freeze
Reset bios by removing coin size battery = no change
I assume there is no use reformatting the HD by attaching it to another computer and re-install Win7. Is it a motherboard problem?

A few days ago I decided to try a linux OS for the first time. Following a how-to advice, I created a ~80gb partition (on a 320 gb sata disk) for Win7 and installed it. Then I installed Ubuntu 10.04, chose to make partitions manually, created a primary ext4-partition (right after the one with Win7) for / and a 1024mb swap partition. So now the disk is parted this way: 512 booter - Win7 system, ~ 80gb ntfs - Ubuntu /, 8 gb ext4 - Ubuntu 1 gb swap - file storage, ntfs ~240 gb (created using Win7 bootable disk, but the issue from below started before this).
After the installation the boot loader failed to load any system, giving the error from the topic title. I tried several ways to reinstall/repair/reconfigure grub in the live-CD mode. Some of them didn't change anything, others were not completed because of an update-grub error ("cannot find a device for / (is /dev mounted?)"). Grub version is 1.98b. The disk with Win7 and Ubuntu is treated as hd0 in grub and sdd in Ubuntu
ote: even though the thread is marked as SOLVED, the issue is actually not. I have managed to dual-boot Win7 and Ubuntu, but with partition configuration changes

error: unknown filesystem grub rescue>
Background: My mother's HP laptop had Ubuntu and Vista on it, Ubuntu my brother's doing. He decided he wanted to take off Ubuntu yesterday (he had forgotten the password), and deleted the partition that it was contained within. The computer now boots to this error.
Inventory: We no longer have the install disk for Windows Vista, he cannot tell me what version he used of Ubuntu, what partition it was on, any of the specs for the machine, or generally any information about the system. All I am aware of is that error on the boot-up screen. I have nothing else to work with.
I would like to remove Grub, and Ubuntu, and leave Windows intact (the request of the owner of the computer), but I have no idea what commands I could use to get rid of either when I can't access Windows, or how to properly remove them if I did access Windows.
