Ubuntu Installation :: Automatic Grub2 Choice On Remote Reboot?
Jan 10, 2010
I'm trying to figure out if I can do a remote reboot (eg over ssh) and specify a new grub2 os choice for the next boot only (once), in order to boot windows remotely once, but then back to linux on the next reboot.I found this related post for grub, but won't work for grub2 ( I never tried it with grub for a remote reboot)[URL]which suggests changing the default menu option with the once flag:
Just got a new laptop with Win7 and downloaded Ubuntu 10.10 to do a dual boot. Ran through the graphical installer setup my partitions and either I missed it or it did not give a choice of where to install Grub2.
Everything is working fine but of course Grub is my boot loader for Windows and Ubuntu which I do not like and never install that way. I have just had too many problems so I normally use EasyBCD.
So the question is, did I just miss the option to install Grub2 on the partition where my root is or did this option change? The last version I used was 9.10.
machine boots straight to Windows, Grub2 does not display the normal boot menu choices. Therefore, not able to boot into Ubuntu 9.10.Perhaps someone could look at this Results.txt file and shed some light on what went wrong.This machine was working fine for a long time, then all of a sudden, it starting booting straight to Windows.
The new version of Slack is on the doorstep and soon it's time to clean up my box.
What is your remote desktop server of choice?
I require a few things: - Linux side server that starts up on boot - Windows and linux side client - Preferably attachable to a running desktop session, although I can live with a server that starts up X - Semi-effortless setup on Slackware (with slackbuilds, maybe)
This far I've used x11vnc, but we don't get along all the time. I was interested to try teamviewer, but so far I didn't find information how to use it as standalone server.
I changed the grub2 on my /dev/sda to Arch's version, instead of Ubuntu's, and now I keep booting into the initramfs prompt whenever I try to use Ubuntu. The automatic OS detection won't find it when I run the mkconfig command on grub2's wiki, and I currently have the following in /etc/grub.d/40_custom:
Code:
enuentry "Ubuntu Linux" { set root=(hd0,3) linux /boot/vmlinuz-2.6.35-23-generic initrd /boot/initrd.img-2.6.35-23-generic root=dev/sda3 ro quiet }
Which according to my partition layout, and a double check on gparted, is correct. Do I need to flag it as boot or something else? I tried putting Ubuntu's grub2 back on with the live cd but it kept saying /dev/ was busy.
I was wondering if there is a way to automatically transfer files between one machine to another upon Debian starting (or when a script is executed). Would it be also possible to check a database for a value and if the value exists then files can be transferred automatically (just like reboot).
I have a problem while rebooting my 9.10 server when I have SAN partition mounted. The message is something about the swap that can not be cleaned during the process. All works if I unmount the partitions before shutting down or rebooting.So I though to create a bash script that unmounts the parts during runlevel 0 and 6.I've created a simple script like this in /etc/init.d:
I did an automatic update and rebooted this morning and I now have a bit of a nightmare situation where I can't open the majority of applications, including the terminal. When I rebooted, my desktop loaded as normal, but then when I try to open the terminal (from Applications -> Accessories or from my quick launch panel), nothing happens other than the quick launch panel disappears for a second then reappears. This is the case for most other apps, but not for Chrome (obviously).
Used Alt+F2 to open the terminal, ran safe upgrade and then rebooted, but still having the same issue. As Ubuntu was booting, there was a "Broken pipe" message, which didn't stop the boot process but is still a bit worrying. I've run a file system check but this hasn't resolved the problem either.
I have a working RHEL in /dev/sda1 and a newly constructed Ubuntu Lucid in /dev/sda2. I'm going to edit the grub config and reboot the server into the new Ubuntu. However, I'm not 100% sure that the new distro can boot. And since my only way to access the server is via SSH, I need the network to be up too.
How can I configure Grub and Ubuntu so that if the server fails to boot, it will automatically reboot into the old RHEL? Currently using GRUB 0.93, but I can upgrade it if needed.
Update: In the end, no boot failure occured. But without the insurance from this, I wouldn't have attempted [URL]..
i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again. i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.

I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?
I recently downloaded grub2 source code for my F13 installation and it compiled and installed perfectly, but when I rebooted nothing had happened and grub was still version .97. Is there something I didn't do?
i have been encountered this issue since ubuntu hardy 8.04.3, and now after i clean installed to ubuntu lucid 10.04 with the latest update up to june 6, 2010, i still could not reboot via command line in a remote ssh.
I have an Ubuntu Desktop machine that I have to frequently access remotely - sometimes after it has rebooted. I'm not concerned about physical security for the machine but I am concerned about remote security.
Since normal VNC isn't activated until after the login, what is the best way to go about remotely accessing this machine's desktop without having hands on it?
I've tried setting auto-login but then I run into the keyring not unlocked problem. Disabling the keyring or setting a blank password seems like a bad idea.
I tried a remote reboot via ssh. I couldn't log back in even though sshd is a startup script, because the KDE daemon wanted me to enter my kwallet password...which is of course part of the DE, not something accessible via ssh. How do I turn off that check or automate it?
I tried searching forums before posting, but it was hard to search due to the specific nature of what I want to do.
I have one hard drive with windows XP on it. Another with Ubuntu. As it stands there is no link between them. Is it possible to create a dual boot using these disks? - I do not want to reinstall any of them. Preferably, I would like the boot choice (or booter? - not really sure what I'm talking about) to be on the newer Ubuntu drive.
It is on an old machine with 256MB Ram. So slow in fact, I'm going to change the desktop environment to Xubuntu - but that's mostly irrelevant.
As I understand it, I should make the Ubuntu drive master, XP as slave... but then what?
Upgraded webserver to Jessie as an upgrade to Wheezy produced errors, and before reboot everything was up and running, but as all upgrade docs and info I read, I rebooted the server. However it never came back. I have the original backup files before I did the Wheezy upgrade. I also have access by Rescue to the server.Made a back up of critical files and have a 24GB tar file and I can connect by SFTP.
how to check the Debian files... Grub etc.. I would prefer to find the issue than start again.I am not able to sudo from Putty. I cannot run apt-get update. I did go to chroot, but then I get unable to resolve host errors and Could not open lock file because Permission denied errors and asking if I am root.There is information by googling for start up issues, but as I am working remotely with a Rescue set up, a lot of the commands I see and have tied do not work.
I installed Lucid Lynx in my p4:2.66 hz machine with XP sp3 pre-installed and the system booted just fine with dual boot option. Then I updated my Lucid. All updates were downloaded. But during update installation a power failure caused PC reboot. Again I started update manager and it gave me option for "Partial Upgrade". I did the same and it instructed me to reboot. The the real damn thing happens now when I rebooted, In the GRUB menu it showed only Memorytest options. I see no OS choice there, I tried to reinstall GRUB from live CD with mount options. And it showed no errors during the procedure. I rebooted but the same problem exists.
So I'm currently On Windows XP professional and want to dual-boot with Ubuntu....
Right, so I downloaded first the ISO for ubuntu here: [URL]
And then proceeded to downloading the windows installer here: [URL]
However after "Successfully" Installing, I do not get a choice to boot from ubuntu on start-up...
I have tried several things;
Re-installing - To no effect Downloading EasyBCD, which tells me that I have No BCD file, and when I opened my Boot.ini file, it was blank... Also, there is no folder C:Boot....
Now I don't know what to do and am scared to re-start just incase it doesn't boot to anything...
Ubuntu and windows 7 were running in harmony prior to a reinstallation of windows 7. Earlier i would get a screen where i could select either windows or ubuntu to boot from. Now, however, my system seems to bypass that completely.
I just upgraded to 10.10 and now I am faced with a choice at boot up of which kernel I would like to boot (or recovery mode, or memtest).I am wondering how to default to the newest kernel without this prompt.
I just attempted to install ubuntu for the 4th and 5th time and have yet again had a fail. This time it actually completed the installation, which is a first. however upon reboot it takes me directly to Vista - I don't see grub or a o/s selection choice.
I installed Ubuntu 9.10 (desktop version) and it performs flawlessly. Now I want to add a second hard drive to the same box, install Ubuntu 9.10 *server* on it, and use GRUB to control which one boots.
Problem is, I'm a Windows pro but a Linux n00b. Should I disconnect the first hard drive (the one with Ubuntu desktop) before I do the server installation on the second (new) drive? Also, how do I edit GRUB's menu to offer a choice between the 2 OSes?
I am new user (or not yet) of ubuntu and this forum . I installed ubuntu via wubu instaler as program of windows xp but I cant run it . I dl-ed ubuntu made live cd , booting from dvd-drive is working normally , and my instalation via wubu was fine . Now when I start my pc choice is shown to me on desktop :
-Windows XP -Ubuntu
But I cant make choice coz windows aint reacting on keyboard . Cant use my arrows to make choice . I got stuck here , I would like to install ubuntu as main OS but I think it is too early since I am newb and just started to learn pc science and programing . I hope to use it just as Windows program at the beggening .Later when I get used to it and learn how to properly install it as partition for itself I will do so .
I was using Ubuntu 9.10, until I got a new graphics card (Nvidia GeForce 9800 GT). After I got that upgrade, Ubuntu no longer supported that card for some reason, so I decided to try Linux Mint since it was a close relative to Ubuntu. Still no support for the video card.
I've always wanted to try Fedora so I decided to grab the x86_64 live cd and burn it. I stick it into my disk drive and it boots where it shows me the options to "Boot" "Verify and Boot" "Boot from Hard Disk" and one other option.
I tried the Boot option, and after selecting that, everything stalls, and my display turns off (not the entire monitor, just the display). I tried Verify and Boot, and still no luck.
I have also tried the i686 live cd and the same issue. It can not be the way I am burning it, cause I've gotten other live cd's to work with the same method of burning. Is it that Fedora does not support the card?
I am trying to get the GNOME version up and running.
I can't install with the ext3 or XFS file systems. It will only let me install with ext4. I have used both a live CD and USB.Someone help me find out what I am doing wrong, I would like to have my ext3!
-Fedora 13 -latest kernel -used Live CD and Live USB (UNetBootin)
i'm trying to intall an old etch debian release using the netinstall netinstall debian-40r9-i386-netinst.iso. But i've got an issue while configuring the miror. Here where i'm blocked (it seems my archive miror is not right but why ?): in the previous screen, i entered the right path (i think): and as you can see in my screen cap of the broswer, the website of the archive is right, so where am i go wrong ?:
I am so close to the answer i think. My goal is to fully automate an entire Ubuntu installation off a usb flashdrive from start to finish. So, i did as this guide said and i made a kickstart ks.cfg file that is used to automate an installation, as i'm sure many of u know.The next step has infinitely confused me. To make the ks.cfg file boot automatically and startup an installation to my specifications.from this linkttp://old-releases.ubuntu.com/ubunt...en/apcs01.htmlI have found that editing the syslinux.cfg file in the syslinux directory on the usb can be used to load preseed file, which to my understanding serves the same purpose as a kickstart file.
