Ubuntu Installation :: Lost Grub Boot Of Windows XP / Getting Blank Screen With A Flashing Cursor?
May 1, 2010
I have just updated to 10.04 on my Dell Insperon 8200 laptop, and all seems well with Linux.My problem is that although it shows in Grub Windows XP will not load. I just get a blank screen with a flashing cursor.I have tried to grub-mkconfig and grub-update, both of which reported successful results.However on reboot I still get a blank screen for windows.This was not an issue with 9.04 and 9.10.so I don't think it is the machine.
Running 10.04 as the only OS on a HP desktop - been running fine for months. Did an update - probably hadn't done one for a couple of months - may be a red herring. The system appeared to crash while inactive. Trying to boot - I get the Ubuntu 10.04 screen for a short while then it goes to blank screen with a flashing cursor at the top - occasionally it will give me an error that /home is not ready - skip or manual fix. I have sda1 = ext4 root
sda2 = swap sda3 = ext4 home sdb1 = ntfs
I removed sdb1 from fstab as initially it was complaining about this drive not being ready. The error switched to complaining about /home. I am able to mount both of those filesystems with no problem manually. I ran mke3fs on /home (I forgot the -n parameter! but no problem as I have good backups) - same error - complains about /home not being available at boot even though I can always manually mount it from live cd or manual recovery. I can rebuild this system - and I may as it was upgraded from 9.10 - I may do a fresh 10.04, but I would like to fix the boot problem in case something like this happens again when I actually care about fixing it.I recreated the grub2 configs - I don't have the command to hand, something like: sudo update-grub --root-directory=/mnt/boot/grub /dev/sda
I recently installed Ubuntu 10.04 on my Aspire One netbook, but everytime while booting, I am stuck at a blank screen with a blinking cursor. I've tried reinstalling but to no help. I've also tried installing 9.10, which will boot, then upgrading to 10.04 which then produces the same problem.
I have a desktop with AMD Sempron 3000+, 1.2GB RAM, VIA S3G Unichrome Pro IGP, VIA SATA RAID controller based disks, PS/2 mouse and keyboard running Windows XP. Wanted to move to years ago favourite (linux based systems), I downloaded Ubuntu 10.04 for i386 and am trying to install both using CD as well as USB. After the Ubuntu start-up menu for installation, I select install Ubuntu option, turn off 'quiet' so that I can see what happens. The screen goes blank dark with a flashing cursor at the top.
In the kernel messages, the see that it has detected the processor, set the clock, assigned the PS/2 keyboard to input3 and then says: [1.911624] isapnp: no plug and play device found After this, the system hangs. Keyboard doesn't work.
I've just installed ubuntu 9.10 from a live cd on to a 2nd HDD, with vista on the 1st. When I turn my PC on GRUB comes up and I can select ubuntu or vista, vista works but when I try to boot ubuntu the screen goes black with a small flashing underscore in the top left and then just goes completely black, nothing else happens after this. I've tried reinstalling from the live cd but when I go install nothing happens and the screen goes black again. When I was installing I changed the boot to something like scsi?
My PC's specs are: Dell inspiron 531 HDD1: Ubuntu(300GB) HDD2: Vista(1TB) OS Windows vista Graphics card. ATI radeon HD 4700 series
Slack 13.0 X sometimes fails to start after boot about 50% of the time. linux says "starting X11 session" then I get a blank screen with a flashing cursor and absolutely nothing else. I can <ctrl>-<alt>-<F7> and get a text prompt, log in, and startx from a command prompt. After that, I can reboot once or twice and still get a graphic login, but will soon revert to the dumped condition. I have reinstalled X and KDE twice now as well as deleting my .kde folder. This condition started when I inadvertently ran out of disk space on my /home drive. Since then I have migrated /home to a larger drive and watch it's disk space very carefully.
I recently followed instructions to enable the nvidia driver. run the following commands:
then rebooted, a tricoloured loading bar appeared and finished, then all i got was a blank screen with flashing cursor. I don't get a prompt to login and can't access my account. I am dual booting on this machine with ubuntu, is there anyway i can restore my fedora partition and enable my nvidia graphics
I installed Ubuntu a while ago, but sometimes (about half the time), when I boot my computer, go into the Grub bootloader, then whether Grub selects Ubuntu for me (not sure if this is an error as well, but I've found that if I leave it without pressing any keys, then Grub just boots into Ubuntu for me (also, it's the top option)) or I select Ubuntu, it then flashes a cursor (a '_' character) on the screen (it's also in the same font as the font used by BIOS, so I assume at this moment, it's in BIOS).
Next, one of two things happen. Either I have to wait a few seconds, then it boots into Ubuntu, OR, it just hangs like that, not booting into Ubuntu, and not responding to any key presses or anything, forcing me to power off my machine using the hardware button.My specs, generated from hardinfo, are:
Code: -Computer- Processor : 2x Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz
I installed Fedora 11 today, because I'm really looking to replace Windows. I've been running a Fedora 11 webserver at home for over a year, but this is Linux, which means that I spent about 8 hours on it over a year ago, and then only logged in once or twice since. :P
So after the install, I booted to a GRUB prompt and no menu. After searching around, I changed my BIOS settings to Large for the hard drive, and got the GRUB menu to load, and now I'm posting this from within Fedora 11, and after some good healthy exercises with the soundcard, xvid drivers, and a few other things, it's great.When I load XP from Grub, I just get a flashing underscore and no progress.XP is installed in the first partition, and has been there for a few months. Here's my grub.conf:
I dual-boot Windows 7 and Ubuntu. Sometime between 4/18 and a few days ago, something happened with Windows booting up. Ubuntu boots fine, but whenever I try to boot Windows, it just goes to a black screen with a blinking cursor (the command line kind, not a pointer). At first I thought it was Windows, but I have run the repair CD and executed chkdsk /f and chkdsk /r on all partition related to windows. No effect.
I ran a system check designed for issues with booting up, and it found no errors. I have looked at my GRUB files, and they all look fine. I am not sure if it is GRUB or Windows. I tried reinstalling the Windows boot-loader, and it had the same effect, the only difference is that it bypassed GRUB. The reason I think it may be GRUB is that the error happened around the same time as me upgrading from Karmic to the Lucid RC. I have posted this on a Windows 7 forum.
I have just wiped my whole hard drive to install a fresh copy of Ubuntu on it, and now as soon as i power it up it passes the POST screen and black screen shows up with a flashing cursor. I bliv it should say no operating system and pick the USB which has Ubuntu installation on it.I have formated the hard drive to NTFS, the system is Samsung NC10.
After installing Ubuntu Server 10.04 LTS, I restarted my machine. I removed the disk, but now when it starts, it never gets to GRUB. Instead, it just takes me to a black screen with a blinking cursor. I can't type in anything and holding shift doesn't take me to GRUB.
I recently wanted to install ubuntu 11.04 on my computer (which had vista on it and I wanted to just completely wipe that out). After the install I noticed that my monitor would not receive signal during boot (I heard the little drum noise but my monitor said no signal). So I tried following these instructions (which have worked in the past): [URL]
but when I boot the computer I don't have a GRUB menu! It just automaically starts booting ubuntu 11.04. Is this because that is the only OS I have installed? Did I do something wrong? What can I do to fix the problem?
I am trying to install Ubuntu Server 10.10 on a computer with 5x 1.5 TB HDDs. I went through the process of partitioning the five hard drives into three partitions each:
sd*0 is a 300MB partition for /boot, RAID1, 2 active, 3 spare sd*1 is a 500MB partition for swap, RAID1, 2 active, 3 spare sd*2 is a 1.5TB partition for /, RAID5+LVM, 5 active, 0 spare. md0 is the raid1 on sd*0 md1 is the raid1 on sd*1 md2 is the raid2 on sd*2
During the install, everything seemed to work fine with the formatter, but the installation ended in error. I booted into rescue mode and found that though all the drives were U (in /proc/mdstat), it was resyncing. I let this run (overnight) and the next day, jumped back in and installed the OS successfully.
However, after installing GRUB, when the installation process asked me to reboot, the system came back up with a blank screen (blank, save for a blinking cursor) and didn't move from there. I am thinking that the problem is GRUB, since I can boot into the main LVM partition via the rescue option on the install cd. Here's what bugs me:
I cannot install Ubuntu 10.04, or even boot into the live CD. I'm not an expert, but I've used Ubuntu for several years, and I'm pretty sure I'm not doing anything stupid... Here's what happens when I boot with the Ubuntu 10.04 live CD: I get a purple screen with just an accessibility(?) symbol at the bottom (this lasts 15 seconds). The screen goes black, with a flashing cursor, then changes back to purple, this time with an Ubuntu logo, with 5 dots acting as a progress indicator (this lasts about 1 minute). The screen switches to standby. The CD drive continues to make noises for another minute or so, then stops.
I physically removed my graphics card (ATI Radeon HD 5770), and plugged the monitor straight into the VGA port on the motherboard. Now the CD boots up fine. I could try installing Ubuntu at this point, while my graphics card is unplugged, and then plug my graphics card back in, and see if it starts working then.
On my dual core AMD with 2 gig of memory I installed Lubuntu in VirtualBox for testing and the install was very smooth. My primary OS is Ubuntu 10.04 and it runs sweet. When I boot the Lubuntu virtual machine all I get is the arrow cursor and a blank screen.
I recently installed Ubuntu 10.04 and now when I attempt to boot into Windows, it just goes to a blank screen. I have some stuff on my Windows partition that I would prefer not to lose (documents, bookmarks, etc.)
I tried running
But same result. I also followed the instructions here to create a Boot Info script. Results attached.
When i use my computer (whether it's going online, typing, playing a flash game, or coding) I get these "Black Flashes" that are becoming longer and more frequent. A "Black Flash" is when my computer screen turns blank (but you can still see the backlight) and i have to press the NUMpad ENTER button, shake my mouse furiously, or click my mouse, which sometimes causes undesired actions, but gets me my screen back. sometimes the Black Flashes last a milisecond or 5 seconds or i have to hold the power button and restart because it won't come back on.
I am a complete Linux newbie and I tried installing the latest release candidate (10.04) as a dual boot with Windows XP. The install seemed to go fine and it said it needed to reboot to finish the install. It rebooted and then displayed a series of errors on a DOS-like screen (which I wish I wrote down). When I realized that it was definitely hung, I then held the power button to shut it off. After that, all it does is boot to up to a blank/black screen with a cursor.The box is old and I was actually going to throw it away, but I figured this was a good opportunity to give Linux a try. At this point, I'm willing to go to either Windows or Ubuntu... I don't really care which. I actually just want to recover some files on the box
I have had a working ubuntu 10.10 installation for about 2 months. I had it set up really nicely with my TV card and xbmc. I was really happy until I tried to boot it the other day to show a movie to the Mrs. All I seem to get is a flashing cursor after the initial grub selection. This is the same for both recovery mode and normal. I have booted it after editing the boot selection to removed the quiet splash and it seems to hang after a line that says some thing like "usb 1-4.2: new low speed USB device using ohci_hcd". The machine boots fine in to the Windose partition or in to a live CD.
I have done a bit of searching and I am struggling to find a good step by step troubleshooting guide. I dont really want to blat my setup but it would teach me a lesson about documenting things and blindly doing upgrades. I have included the results from my boot info below in case that points to anything.
Not a major issue but my Ubuntu boot screen change to the old classic Orange theme after i installed Kubuntu on a different drive and ofcourse a new Grub loader as the Kubuntu installation prompted. It can't be because of the Kubuntu installation but i can't find any other reason for that to happen.
I have installed today Ubuntu 10.4 LTS ..after installation the OS does not boot and just shows blank screen with cursor blinking ...any idea ..I have searched the forum a lot but cannot understand why this is happening ..re-installed twice ..This is AMD64 bit but I am installing the 32 bit ubuntu 10.4 LTS.
My new PC fails boot when having my IDE DVD drive connected. If the drive is removed the OS boots up without any issue. Once the PC is powered ON, the grub menu shows up, but when Ubuntu 10.10 is selected I get a blank screen with a blinking cursor on the top left corner and I have only option to force shutdown the CPU.ON selecting windows 7 i'm able to boot successfully and use the DVD drive without any problems.
I have installed it from usb as the cd installation failed at the point where you decide which type of installation you want (lamp or samba, etc)the installation completed but when booting nothing happens, only a black screen with a blinking cursor. pressing the shift key or any other keys doesn't work.strangely when i boot from the usb flash drive again (and not from the hard drive) the server does boot and asks for the user name and password!i have chosen the guided lvm partition with 20% reserved for system files.my machine is an athlon xp 2GHz (32bit), 1GB, SATA hard drive, nvidia 6600 graphicsmy guess is that its a problem with grub and lvm.
when I fired up the installer, after asking to test the media (which I skipped) and starting up the actual installer (anakonda, akonadi, whatever the name was, can't remember now and too lazy to look it up), it seemed to start up fine, except I couldn't get the wizard to show up. I did see the cursor, and occasionally I would get the "searching for storage devices" message (I restarted it a few times to see if I would get it working), but nothing. I also tried random key presses (namely F12,F1-F4), and after some time got a message saying that I had to enter the root password, so I presumably got to the root password screen blind...? (meaning that the installer apparently is ther, I just don't see it?)
After several restarts, though, I managed to get the wizard visible (just luck?), so I went ahead with it, but apparently I messed it up, when I rebooted I didn't get the screen visible again, after some random keypresses I got to the login prompt but I obviously hadn't created any accounts, so :/ I tried booting from the DVD to the rescue mode and manually adduser-ing from the console, but when I tried logging on, it would just come up with some kinda bluetooth-related error message and then hang on there with only the background image on the screen. I didn't try the basic video driver thingy yet because this didn't seem like a video driver issue (well, not entirely anyways), and I need my 3D acceleration, so...
Basically, I'd be glad if anyone knows what's up with the installer, and if it's not fixable as such, would installing with the basic video driver and then installing the proprietary drivers afterwards be all right? Sorry for the wall-of-text, though, it's just one of those days, it's bedtime and I get carried away...
When I try to start Fedora 12 all I get is a flashing cursor on thep LHS of my screen.This is new. Fedora 12 workd fine up until yesterday.treat me as a novice and if you start using technical terms I will just be lost
