I have window 7, Ubuntu and Cent Os installed in my system. I was actually trying to change boots options but unfortunatly i lost all boot entries. Is there anyway i can recover all three boot records.
View 7 RepliesDual Booting my laptop and unable to change the Boot Records on the drive. Not because I dont know how, but my primary OS will fail to boot(win7).
I have drive partitioned as follows...
sda1 = Win7 system (default install)
sda2 = Win7 Main (default install)
sda3 = swap
sda4 = Extension (I think thats what its called)
sda5 = / (ext4)
What I need is a boot cd or perferably Grub installed on a 256MB Thumb drive with the options to load the installed system from sda5.
Have been running ubuntu for sometime now and love its functionality...However since a recent update have the following issues..When I power on the laptop I get the toshiba logo followed by grub loading with the message ' invalid enviroment block" "unable to load default boot entries". When I then try to run the laptop off a LiveCd, the ubuntu splash screen appears with the loading process bar (horizontal line) displayed..however it then appears to display a black screen with no further activity..Now all of this is via an external monitor as my laptop screen shows no activity right from the very start with just a blank screen....so am really stuck here wondering if its a harware/software issue or a combination of both...

View 1 Replies View RelatedI have an existing WinXP install on the main drive (/dev/sda) of a Dell laptop. I installed OpenSUSE 11.3 on the second (caddy tray) drive and didn't touch the existing windows partition during install.After install completed, I found there was no boot loader entry for WinXP during startup. Only SUSE-related stuff. I opened YaST boot loader and tried creating an entry of type "other" and device of "/dev/sda1" and set this as the default entry.The /boot/grub/menu.lst file now has an entry:Quote:
title Windows XP-32
rootnoverify(hd0,0)
chainloader (hd0,0)+1
[code]....
So my grub menu is showing several selections for each of my OS's. In Ubuntu, my OS of choice for now, how can I access the grub and edit it.
I would like to know the steps for console, but also I hope somebody can show me how to use Super Grub to do it.
i am write in the forum because i am a bit of resignated. i tried almost all distries and just suse i can install on my notebook without any problems. actually the install works on all other linux deviantes too but the boot records arent written - except for opensuse - but i dont like opensuse. ubuntu is the system which i have choosen and makes a very handsome impression to me. but back to the main problem my notebook is a sony vaio with 4x64 GB SSD cards. 2 ssd's - raid 1 with windows 7 and the other 2 ssd's (volume1) should be ubuntu. the devs are in /dev/mapper/isw_bic_fifbgib_Volume12 till volume 17
i tried to install the boot files to mbr, on volume1, volume2 to the /boot, to a sd card, to a memory stick but ubuntu wont boot from SSD. i just can boot with cd but its not a option for me.
I have two partitions Windows XP (which was already installed before Ubuntu) and Ubuntu 9.1 (which I installed later).Now the XP doesn't boot anymore (sorry but I need it sometimes), the Windows screen with the progress bar appears and then it reboots after a couple of secs.
I can access to the XP partition from Ububtu.Of course I don't want to damage Ubuntu during the XP recovery action.
I wanted to know the solution that if my linux crashes then can I recover my windows in adual boot env.

It goes to the Windows start screen goes blank, and loops there infinitely. Is there a USB tool I can use to figure out what went wrong and recover either my Windows or Linux partition with out having to do a complete reinstall?

View 3 Replies View RelatedToday I was forced to reformat windoze and of course lost grub so I can't boot ubuntu 9.10. I found two suggestions in previous posts which didn't work. One suggested using the install disk as a rescue disk and as root run grub. I entered sudo grub and the cmd was accepted but the cmnd grub was not found.
The second was to sudo grub -install and again grub was not found. Both these suggestions were for a win 98/mandrake installation.
Do I have to reinstall ubuntu? If so there is a problem in partitioning. Setup sees there is already an ubuntu os on the disk. In fact two of them. I forget why, but I reinstalled ubuntu and ended up with two in the grub menu. I was advised not to try to repair grub and didn't. Now I have two and it thinks I want to put the third one side by side, or erase and use the entire disk. There was a third choice but I forgot already exactly what it was and didn't like it anyway. If I erase and use the entire disk, won't I lose windoze? If I put them side by side I will then have three which which will waste disc space. The discs aren't that big being only about 10gb. I don't think I want to waste the space with a third ubuntu.
Just installed Ubuntu 10.10 on dual boot computer. Each OS is on separate hard drive with GNOME selection between Ubuntu and Windows 7 Ultimate. Firefox was working fine yesterday when I went to use today, nothing. Email through Thunderbird is down as well.

How do I go about doing it? Do I rename "30_os-prober" in /etc/grub.d/ to "10_os-prober" and "10_linux" to "30_linux"?
I just installed a fresh copy of 10.10 - i used the erase entire disk and use for 10.10 option after having earlier troubles of the same booting into 10.10 after installing it over the old / partition. it says:
error: couldn't read file.
error: you need to load the kernel first.
Failed to boot both default and fallback entries.One partition, of 10.10 and no idea where to go...
I have PC with following specs:
Intel E7500 CPU / Intel G31 Motherboard
Kingston 800MHz 2GB RAM
Hitachi 500 GB SATA HDD + Seagate 160 GB SATA HDD
I initially had only 500 GB HDD. I installed two installations of Windows 7 Ultimate - one 32-bit and one 64-bit installations. Both working fine.
Later on I installed the 160 GB HDD and installed Fedora 13 in it in a partition. The rest space of the 160GB I am using with Windows for storing data.
Now, the boot entries of both Windows installations are in the Grub Loader of F13. Means, if I remove the 160GB HDD, I cannot boot into my Windows installations.
Now I want to remove the 160 GB HDD and install a new 2TB hard-drive. That way, I cannot log into my Windows. And I do not want to lose the Linux installation also.
How can I remove the 160 GB HDD and install a new one without sacrificing my Windows installations?
OR...Is it possible that I can copy complete image of F13 on to the new HDD, so that things are same for the Windows installations?
I'm not at all sure what happened, but now Ubuntu won't boot. A program just froze (as programs often do), so I shut down and rebooted, only to find pages and pages of gibberish about ATA sectors and stuff when I tried to get GRUB to load my usual Ubuntu platform (Karmic Koala). I tried "recovery" platforms and older ones, but no luck. I'm now using the Live CD and I've found an error saying "DISK HAS MANY BAD SECTORS" about my '160GB ATA Hitachi HTS542516K9SA00'. It apparently has 109 bad sectors, and the Live CD's assessment is that I "replace the disc".
View 4 Replies View RelatedHad Ubuntu 10.10 running fine on a Dell box, shut down as normal earlier in the week but now won't boot from GRUB (ends up with Busybox screen and initramfs(?) prompt). PC is a dual boot system which still boots OK into the XP partition on the same hard disk. I've tried all the other Unbuntu boot options in the GRUB menu (older kernels and the 'recovery' / non-recovery options) but all produce the same failure to boot into Ubuntu. I've searched the forums and tried various things but nothing has worked so far.
I tried the fix of booting from an Ubuntu 10.10 live CD, creating a mount point and mounting the relevant linux partition before using #apt-get update and #apt-get upgrade options to repair the installation. This seemed like a logical simple solution BUT the partition will not mount!! Further investigation using the Disk Utility app in the Ubuntu drop down menu indicated an error message along the lines of 'cannot mount Daemon inhibited' which I can't seem to find much information about fixing.
Using Gparted it looks like all the partitions originally set up on the disk are still there.
I put a lot of time into getting the system set up (scanners, printers, webcams and software) and would be really annoyed to have to do it all again if at all possible ...
During install, I chose to not install ANY boot records, fearing overwriting my Windows 7 MBR. Now I know otherwise, but to save a couple hours of install, please tell me:How can I install openSUSE boot after-the-fact?I cannot boot into openSUSE.

View 1 Replies View RelatedI recently installed 11.1 via unetbootin from the network onto an old Sony VAIO laptop. After the installation completed, I suppose the OS started to boot, but I was presented with a black screen. I heard "chimes." The black screen does not provide any visible feedback from mouse or keyboard input. I hard rebooted and was presented with an interesting background graphic (grayish, I think) that faded to the same black screen.
View 9 Replies View RelatedI downloaded Ubuntu 10.10. Initially, I had the problem on the "Who are You" screen and was told that lower case letters were needed. Long story short, I was given a work-around since there was a partition on my hard drive. Ubuntu installed correctly - works just fine. However, upon booting up, if I choose Windows 7, it takes me to Recovery and wants to reinstall factory specs. What's the best way to resolve this? Is going back to factory specs and then reinstalling Ubuntu a viable option? This is brand new computer and I've downloaded nothing - wanted to make sure everything was working fine before I did that - so I would have no problem with doing that.
View 9 Replies View RelatedI followed the instructions from this post to reorder my boot options.

View 9 Replies View RelatedPreviously I'd installed Ubuntu Netbook Remix (Lucid) on my Acer Aspire One 751h netbook. the machine came with XP installed, so I installed Ubuntu as a dual-boot setup. I had various problems with the configuration of Ubuntu (nothing to do with the boot process, and now solved) so I reinstalled it.
What I'd actually done with the second installation was to install it again alongside both XP and the original Ubuntu installation (maybe that was also a stupid thing, but I didn't know it would work like that). When I realised what I'd done, I did the stupid thing, which was to delete the partitions with the older installation and swap file (using the Disk Utility).
After that, the next time I rebooted I went straight into grub-rescue. I don't know much about this, but I found a forum entry explaining the basics, so I can now issue grub-rescue commands that let me boot into Ubuntu. I've run update-grub and my /boot/grub/grub.cfg file looks fine.
However, I think this only kicks in once I've got past the initial boot menu and have chosen Ubuntu (now on sda5 - hd0,5). My problem is that the files/processes that load the boot menu on startup still have the old configuration, so when I reboot I still go into grub-rescue and I get 'partition not found' (or, since I recreated the partitions, 'file not found') and root is at (hd0,7).
Is there a way, once I've got into Ubuntu, of changing the information in the startup boot menu Alternatively, if I copy my entire file system from sda5 into sda7, would that do the trick?
My laptop setup is:
sda1: W7
sda2: FAT16
sda3: /boot
sda4: encrypted LVM with debian (everything besides /boot)
now I've re-installed W7 so grub was overwritten. I've tried the procedure which worked for me previously:booting with the netinst usb in rescue mode, choosing a root partition to mount, using grub-install to reinstall the grub:
Code: Select allmount /dev/sda3 /boot
grub-install /dev/sda
Now I'm on Jessie (stable), and this time this fails, and I am able to mount only sda3.grub-install doesn't exit so I'm assuming it has been replaced by `grub-installer'. also '/boot' doesnt exist so I created it manually.
Code: Select allmount /dev/sda3 /boot
grub-installer /dev/sda
The latter fails with
Code: Select all/dev/sda/proc not a directory
I would like to recover my grub installation in a dual boot system. if there is an easy way to recover grub using flash disk? If yes is your suggestion opensuse developed? (currently running 11.3) . It would be nice also to have some gui just to make things easier. If not I assume that then the only option is the boot from dvd. Is that right?
