Ubuntu :: Can't Access Hidden GRUB?
Jan 22, 2011
Once upon a time i hid the boot loader by setting the default boot to windows 7 and the waiting time to 0. However, i can't seem to access it anymore... When i hold shift on boot, nothing happens. When i hold esc, my computer starts beeping like mad if i hold it too soon, but if i hold it later, it just goes to the windows boot thing and reboots. So.. is there anything i can do other than downloading the whole OS again and making a live CD? (don't have the old one anymore)

I was installing Ubuntu on my new laptop (with plans to dual boot with Win 7) and, I'll admit, I did something stupid. You see, there was a 1 meg free space before the Windows 7 'hidden partition' and it was driving me nuts. So, what I did, was use gparted to move the hidden partition to the start of the drive (yes, a 1 meg move). Install of Ubuntu went off without a hitch, but after reboot things went a bit differently. The Recovery partition shows up as a possible boot partition in GRUB, in Windows 7 I can now see the recovery partition as a normal NTFS drive, and I can no longer use the features that the partition gives. I know this might be more of a 'ask on a Windows forum' question, but I was hoping someone else had done something like this and knew how to restore the hidden partition to being, well, hidden.

I had Windows on my machine but I decided to try Ubuntu 11.04. I kept my partitions where I store music, movies and stuff and it is OK, I can open anything, but I can't open the files that were in a hidden folder. I see then, I can browse my Windows hidden directories, but I can't open the files!

I installed Ubuntu netbook remix 9.10 and it ran fine. However, the boot menu is hidden and by default it always boots into Ubuntu (I don't know.. maybe the timeout was 0). I wanted to switch to a different kernel so I compiled a new kernel and installed it. But upon reboot it would always boot into the old kernel. So I updated grub and made the new kernel the default.
Now the new kernel is givine me a kernel panic and I can't access my system because the grub boot menu doesn't show anything (just boots into the newly compiled kernel and gives me a panic message). I don't have a recovery cd/usb. Is there a way for me to somehow slow grub down or show a menu? Pressing esc at boot doesn't help.

just a general weirdness, but some folders that are in my /home folder don't show up. if i check "show hidden folders", they still don't show up. for all terms and purposes, they are simply not there. however, if i search for them through the search tool, or beagle, they show up as being in my /home folder. so, anyone have any idea how this happened, or how i can remedy this?

Last time,I changed the icon for the ding-dictionary,it used the gear-wheel symbol before. The I saw,that the hidden directories also used the new icon,and now they are all gone Did install the old 256.53-NVIDIA-driver last night,but that should not be the reason ?

My Main goal is to get to important data in the HDD which I hope can be backed up in a USB so I can then reformat and reinstall Ubuntu.
Ubuntu version 9.04 (Jaunty)
Pentium 4 PC Desktop
20gig Hardrive
Dedicated Ubuntu, no dual boot or anything, the HDD is fully for Ubuntu only and partitioned that way. 1st Problem: I encountered an error while using Ubuntu and OOffice, so I restarted. Right after the restart I got an error:
[code]...
I researched this in the forums, and the suggestions are to boot with a LiveCD and fix. Unfortunately I have just burned a liveCD now, though I was able to make a liveUSB, and plugged it in. Problem is that during the boot up of LiveUSB, I encountered another Error:
[code]...
Above is problem no. 2 At this point I gave up trying to recover Ubuntu, so I'm just in data recovery mode. My goal as mentioned is to get to the files, back them up and start from scratch.......

I just installed ubuntu on a remote windows server, using wubi. How can I launch ubuntu? Restarting the remote machine obviously disconnects my session. Is there some way to access the grub menu from windows?

I've been using Ubuntu for a couple years, and have really enjoyed the experience. Recently though, I also felt like installing Arch Linux onto my laptop which already had a Vista/Ubuntu 10.04 partition. In doing so, I lost access to the Ubuntu partition on my hard drive. The Arch linux grub had replaced the Ubuntu grub.
So the main question is, does anyone know how I could re-access or re-install the original Ubuntu grub? If not, then can someone help me with adding a boot option in Arch's Grub? I've already tried some things, though obviously, none have worked so far.

I just updated to 10.04 LTS & I would like to edit my grub menu to get rid of the unneeded entries.
When I enter /etc/default/grub into terminal It gives me bash: /etc/default/grub: Permission denied.
From what I have read I just need to put # in front of what I don't want to see in the menu, but I'm unable to access the file to make the changes.
I would also like to make a backup of the file first before editing it.

i have 2 hard drives connected to sata ports randomly on my motherboard ( i didnt do it in any order )
1. Western digital 500GB - Windows 7
2. Seagate 500GB - Linux HDD - had ubuntu 10.04 on it before suse
Ok basically, ive been trying distro's by installing them on my linux HD, my favourite is ubuntu, but i wanted to see what else is out there so i tried out OpenSUSE, and with suse i unfortantly came across many problems with grub-legacy, and i solved that eventually by changing my boot hard disk in BIOS to the seagate, and installing grub on that Ive never had a grub issue in the past using ubuntu, only with suse Then i decided to go back to ubuntu because everything just works and i like .deb packages, so i installed 10.10 32Bit
Everything went fine, chose default install options, formatted the Seagate drive, and installed to the seagate, HD changedt the boot drive to the western digital in BIOS ( were ubuntu likes to install grub in the past ) booted fine, installed fine, grub showed fine, booted to linux then i went back to windows for a day of gaming and fun, i just rebooted about 30 minutes ago to play with linux, and i cant access the grub menu my pc goes to the POST screen and then were grub should show, i get a blank screen and the pc just reboots to the POST constantly this problem has never happened with ubuntu, ive had 10.10 before, this is all started after removing opensuse
ive tried F8 and booting from both drives, the seagate i just get a white underline for ages and nothing happens and i cant boot to windows on the WD Im currently on my livecd im using the 11.04 livecd, all my cds arent labelled, so i have no idea which is which, i just chucked one in to get a browser, but i gotta say natty 11.04 IS AWSOME

My machine is an hp 2133 mininote. It came factory installed with Windows vista, which repeadtedly crashed on me. To compenstate for this i installed gOS to dual boot with Vista. This was working fine but I was recently given a Windows 7 install disk, so I decided to upgrade. Windows seven installed without a problem but now I can't access the GRUB bootloader, windows 7 just loads automatically. I tried to restore it using the Super GRUB Disk usb utility but it didn't work, windows 7 still boots regardless.

I can't access my grub menu (by pressing space bar on boot) to select a kernel to boot from, and I need to boot into 2.6.31 to fix an intel chip issue. How can I replace the current 2.6.32x kernel with 2.6.31, so it is the ONLY option grub can boot up with?

with that said i burned fedora 8, 10, and 11 checked the sha1 verified everything was fine i had originally installed fedora 8 on an old pc i had from windows XP without any problems messed with it some, upgraded to 10 again no problems. tired to update 11 got a message about ext3 not found ext4 not found, re installed 10 the loader loads up now i have a blank screen with a cursor it the left hand corner
again i had 10 installed fine prior to all this can any one point me in the right direction to solve this issue or am i way over my head trying to figure this stuff out. i have spent 3 days searching these forums.
i'm just not quite sure what i need to do. oh, i tried to install 8 again and it wouldn't take either. i think the 10 problem has something to do with the graphic driver it's a geforce 7400 nvidia and something to do with the grub, but like i said i get a blinking cursor and not quite sure how to access the grub or command line.

I just upgraded from 9.04 to 9.10 (using Update Manager) in an attempt to get to 10.04. Installation and upgrade seemed to go OK until reboot. Now I only get a black screen - I don't see the grub menu, I don't even see any way to access the BIOS menu- not even a blinking cursor. I can hear it start and I can see the numlocks key go on. Ctrl-Alt-PrtScrn-B does not reboot (nor does Ctrl-Alt-Backspace- but I didn't expect that would) Surprisingly Ctrl-Alt-Del does (or at least it sounds like it does) reboot the system. I do have a NVIDIA cards and after reading around I suspect that this is likely the problem but I have no idea what to do now..
Here's what I've attempted:
I figured since I wanted to get to 10.04 anyway and this was so troublesome I could just go do a fresh install with a Live CD or USB to 10.04. However, even with a live CD or USB I still just get a blank screen.
Continually holding down F2 (and other function keys to try to access Bios)
Holding down Shift while booting
Esc while booting
Moving the monitor to the VGA port (as opposed to the NVIDIA card).
Other information...
Previously I had tried to upgrade to 9.10, but ran into problems with it not recognizing my RAID, so I just found it easier to go back to 9.04. (So although this is likely a graphics problem I guess the possibility is that now it doesn't even see my boot drive- although- if that was the case, I'd assume I wouldn't have the same problems from the CD or USB boot.) My ultimate goal is to get this to 10.04, if I could do it with an upgrade instead of a fresh install I'd prefer that, but at this point just getting back to a functioning computer would be ideal. I see many options in other posts for how to get back once you can access a command line- but since I can't even see that, I'm not sure what to do now.

When I installed 64 bit OpenSUSE Gnome 11.4 today on an ext4 primary partition (sda4) from the Install DVD, it eliminated LinuxMint 9's entry from OpenSUSE'sGrub The 64 bit LinuxMint v. 9 (Isadora) is installed on an ext4 logical partition (sda9) inside an extended partition, but it doesn't appear in OpenSUSE's Grub (and now OpenSUSE 11.4 won't connect to the Internet - although the Live CD ran yesterday without a hitch).
I'm hoping that my fellow OpenSUSE users can help me regain access to my Isadora installation and hopefully, point me to a solution for the Internet access problem.

I am setting up my test / development machine with the following scenario in mind : I boot the machine and then select one of a number ( e.g. 3 ) boot options in Grub ( Normally "OpenSuse", "Safe Mode" etc., but in this case "System Restore Dev.", "System Restore Test" ). The only difference between these options are the settings ( e.g. "vga=378" ) in these cases something like "distro=dev" / "distro=test".
In a script run on the booted system I can extract the value of the "distro" parameter ( in this case "test" ) and use it as input for a command line tool. Meaning that name entered as the value for the "distro" parameter is used for loading a file when the system is up and running. The command line tool then restores the partition with the contents of the file and reboots the system.Now, my problem is this : How to I access the Grub arguments? Code snippets ( in shell scripting or python preferbly ) are more than welcome.

I have an hp laptop and i had ubuntu on it for 3 years. my hard drive started to fail a while ago (i had ubuntu 10 on it until 1 week ago) and a then it all went black...I took the laptop to a repair shop, they told me it was the disc, so i bought a new disc, installed it on my laptop and reinstalled the new ubuntu 11. so far so good. i have now a working OS, internet connection and i can in fact type this message.
The thing is: all my files are on the old drive, which doesn't load/boot/start/read anymore. I have tested it on some friends's pc, tried a few HD disgnostic tools, they all send the same message: "fail"
I then tried to mount my old drive (with all my precious files in it) on my laptop as an external drive (usb) hoping that ubuntu 11 could read it as an external usb key: it gets read by the system, but it shows no files at all. it also shows an error message saying the drive can not be mounted, with some "sdb1" thing. i am sorry but i'm really dumb when it comes to tech language.
Then i tried to boot it on start-up but i got the grub rescue> thing and nothing else, just a sad, blinking cursor to recover my files,i have also tried testdisk but couldn't understand very well how to use it, and then photorec, from which i recovered bits and pieces of files, with no name. some of them are just parts some of them are complete.
My problem is: i have to get access to my files, as I use them for work, i couldn't do a back-up recently and i have some real important deadline to meet... for which i need those files. is there any way i could solve the grub issue and have that drive load/mount again as external usb?

My partitions are set up as follows:
[code]...
I installed Ubuntu successfully using rescue mode on the alternate cd, and let Ubuntu use an internal boot and home. At the final stage grub refused to install to the MBR, and then refused to install to my /boot partition on /dev/sda2. It said: No boot loader has been installed, either because you chose not to or because your specific architecture doesn't support a boot loader yet. You will need to boot manually with the /vmlinuz kernel on partition /dev/mapper/volumegroup-natty and root=/dev/mapper/volumegroup-natty passed as a kernel argument. Returning to debian, I did a update-grub, which detects Windows and Ubuntu:

How do I make grub decrypt the LUKS partition before attempting to load the Ubuntu kernel?

I would like to know if there is any differences on how to install and to configure GRUB 2 in the different architectures (BIOS/IBM PC-Compatibles, EFI/MacIntel and Corebbot)? Does the Ubuntu installer automatically recognize the different architectures and install the appropriate GRUB 2 package ('grub-pc', 'grub-efi' or 'grub-coreboot' according to the arch)? Or does it just install 'grub-pc'? Is the location of GRUB 2's configuration files different depending on the arch of the computer? Or are they all located in '/boot/grub/', '/etc/grub/default' and '/etc/grub.d/', no matter the arch of the computer? Are the files' structure and options to configure GRUB 2 ('/etc/grub/default' and the scripts in '/etc/grub.d/') different depending on the arch of the computer?
