Ubuntu Installation :: Cannot Get To The Screen That Allows To Choose An Operating System
Dec 2, 2010
I recently upgraded to the newest version of Ubuntu. I dual boot with Windows 7.
All was going fine the first few times I used my system after the upgrade but I have now run into a serious problem. I'm not that technical so will explain this as best i can.
Basically, when I switch my computer on, I can not get to the screen that allows me to choose an operating system. Before it gets there it just restarts.
I guess its a problem with the GNU GRUB software. It just seems like the computer can't find it and restarts itself. So I can't get into either Ubuntu or Windows at the moment.

Will a Linux operating system lose data during a power failure as does a Windows operating system?
(If yes.) This has not come up before but I'm going to be doing some work I don't want to lose.
Could you either point me to a backup tutorial or give me the quick overview of preserving stuff with Ubuntu?

I recently installed Ubuntu in my PC, without uninstalling windows coz it`s not really mine, its my father`s. When he saw the boot (like a month later, he REALLY uses the PC...) he went crazy and instantly ordered me to "uninstall that thing". Of course i`m not stupid to do that after a month of seeing how Ubuntu is... I want to know if/how can I make the pc start on windows auto, without prompting by showing the choose system screen, and when i open boot menu (i don`t remember, but i think its F-eight) i have both choices, so I can keep Linux without him knowing.

I am trying to install Ubuntu 9.10 on an old IBM T21 laptop. It starts very happily, and I am able to partition the disk & copy the files to the HDD. However, when it loads the desktop there is an icon for the CD drive (and install disk). Everything appears to be fine, but I don't see any confirmation of the installation being completed. The CD drive does not open when the button is pressed. When I restart the laptop, I get the message 'operating system not found'. Starting the machine using the CD works fine. The disk shows that the partitions have been created, and I am told that Ubuntu 9.10 is installed.

I formatted my 2nd hard drive(IDE) inside of windows. So I had a clean 80 GIG HDD. I downloaded the wubi installer and allowed it to have 30 GIGs of the newly formatted hard drive. I restarted it and it just used my 250GIG SATA drive. I then restarted and pressed esc. to make it use the 80 GIG and it said operating system not found. I then deleted it and tried again. Same result. I then reformatted it marked it as active and installed Ubuntu again and it did boot the 80 but it said the NTLDR is missing.

after hours of formating C and windows XP and after hours of installing Ubuntu,I can see the desktop backround image, the grey bar on the top of the screen with the sound icon and the ON/OFF button and then my laptop becames unresponsive.Nothing moves, cant here anything... (the cd loading).So, If I restart the pc pressing ESC so I can change the boot order and have it boot from the Hard drive, I get this message: "Operating System not Found".I've tryed to install Ubuntu about 5 times now and both 5 times it goes up to the same point and then stops.

I believe I have an old operating system of netbook Ubuntu and I am trying to upgrade to the latest 11 version. My netbook doesn't have a cd drive. I have tried using UNETBOOTIN with my usb drive (2GB) and have encountered problems with the install.
When I boot in it says" missin operating system". Sorry I don't have time to search I am on vacation and internet is sparse. Also i am loading unetbootin with a iso image of the latest version.

I have been trying to find an answer for the past 4 hours, and I am stressing out right now. I bought a IBM Thinkcentre Celeron 2.8ghz off ebay, and when I turn it on it had no operating system. It says: "1962: No operating system found. Press F1 to reboot." I press F1, and it just did they same thing. Came up with that message.
Then I searched on the net for some answers on how to install ubuntu onto a computer without an operating system, and they said to enter BIOS menu and boot the ubuntu from the USB. So I turned the comp back on, and I pressed every button on the Computer except F1, and it did nothing. I dont know how to get into the BIOS menu.

I am trying to install a linux distrobution on a laptop that can only boot off a cd or harddrive (or network? not sure), except that it has no cd drive and no operating system. That's right, no floppy no USB no CD. I read on the internet a chap installed Ubuntu with these conditions by taking out the harddrive and installing an old copy of Ubuntu on it on another computer with a disc drive, and then putting it back in his laptop and upgrading.
Now I have installed DOS 7.10 before on this laptop hard-drive and it worked, but it wasn't very useful, being a text based system. I have tried installing Windows XP (only because I am familiar with it) but my installation CD is OEM, and doesn't seem to like it. So I put the ubuntu 4.10 cd in my desktop with the CD drive after clearing all data off the laptop hard-drive (DOS 7.10). Then the cd boots and I am given the menu to install ubuntu. So I press Enter, it starts installing and then freezes at the language selection screen. So what is my problem? I have pressed lots of keys in order to get some response, but nothing. I waited 10min for something to happen, but nothing did.

I'm new to Linux and wanted to get experience with Ubuntu Server for my new build NAS, because just a NAS OS wouldn't be enough for me. I wanted a server so I can also setup a PDC and webserver.So currently I'm installing ubuntu server 10.04 onto my newly assembled server via usb stick(didn't build in dvd rom drive) I checked the BIOS before loading the OS onto the computer and everything is detected.
there's 1 thing that keeps bugging me. After installation i get a message that the install is complete and usb sticks and all devices should be removed to prevent it from booting the install again.However when i remove the usb stick and I reboot the server I get the following message on the screen:
missing operating system
or
can't find operating system
When I do let the usb stick in, it boots into Ubuntu Server and i can see all my configurations that I made eventhough during install I chose to install it on the HD and paid attention to it I wouldn't touch the usb stick.From here on i could configure the rest, like samba, and give my server an static ip address via the command line.Back to my problem: what can i do to make my server boot from HD without that I have the usb stick in?

I'm new at Centos, although I am familiar with Redhat.I have a laptop that has Windows XP installed on it, and I want this to run Centos 5.3 instead.I read some tutorials online, where I found the download "CentOS-5.3-i386-LiveCD". I burned this to a DVD-RW. When I put the disk in my drive and look my my D: Drive it reads: DVD RW Drive (D:) CentOS-5.3-i386-LiveCD.>I am burning with Nero 7 Essentials.I place this in the laptop disk drive, bring up the BIOS, set it to boot from CD, and when I boot it up I get the message "No Operating System Found".I also tried this from another computer, Windows Vista Home Premium, and it skipped the priority boot (which I set to CD) and went right to the hard disk, booting up to Vista like normal.I hope I'm just doing something wrong.. When I go into the DVD, I first of all see a folder labeled "LiveOS" - Then inside -> -osmin - IMG File - 12.0 KB-squashfs - IMG File - 677 MB

Basically I had windows 8.1 running on my fujitsu lifebook A532 laptop and wanted to dual boot kali linux alongside it, however upon installing the linux it deleted EVERYTHING! on my laptop, the grub bootloader only showed kali linux to choose from...
I then decided kali linux is too complicated for me and decided to delete everything and reinstall windows 8 again however I was surprised that my bios screen looks diffrent also I can not edit the boot sequence.
If I press f2 or f12 it takes me to a screen with a tab named Boot menu and its written on it debian and every time I press enter on it it takes me back to this same screen...
I can not boot from cd or usb!

On my laptop I dual boot Ubuntu 8.04 and Windows XP. During the last upgrade of my Ubuntu distro something went wrong and now I get a messed up GUI. In the meanwhile I got a new laptop on which I only run Ubuntu 9.10. So my question is: I want to delete the linux partition on my old laptop and use only Windows XP but since I use grub to dual boot, I'm afraid that deleting the linux partition and extending the Windows partition will cause problems to boot my computer.
Here's a screenshot of my partitions:

i tried to install ubuntu on my company notebook, where already xp is installed and I have to work with on monday again ;(I have to partitions 60+60GB with XP and Data. I tried to resize the Boot one to 50 to gain some space for ubuntu. Gparted rezided and moved partition (10unallocated+50boot+60data). I guess thats when the bootloader was destroyed. Now I can not start XP anymore. JaiiXXX! But i have to.
Question now is:
-Would it help to resize again with gparted so that i have 60+60 again and can start working?
-Should i continue installing ubuntu from usb. It is recognizing all partitions correctly and asking to install in dualboot. howeber i guess, when bootloader for xp is not working now, will it work after installation of ubuntu on the 10gb or will it make things more complicated?
-My tummy says first to repair windows xp an then install ubuntu. I have no xp cd since it is company computer. will repair morde work with another xp cd? i would prefer that. i saw that there is another way b reinstalling the xp by bootloader, but it sounds to complicated to me and i am little nervous now.p.s. i recognized that now data partition is flagged with boot . dont know why but put it back to the right partition, nothing changed.

So I was installing 10.10 to be my only operating system on my 3 year old custom built computer and all of a sudden it stopped working at the point of "whenever you are ready" but not letting me go forward because it still was loading. I waited a long time and it was frozen so I restarted my computer and now I don't have anything on it. No operating system at all. Except the symbol " _ " blinking rapidly. Nothing is working and I just want to run 10 on my desktop

I have just installed Ubuntu 10.04 on a Fujitsu Amilo. After removing the DVD the computer is not able to find the booting on the onboard hard-drive. I get the message "Operating system not found". My first try was from a USB stick, after that I installed from a DVD. I get the same result also after downloading again. What to do. I am confused. I have done the installation on 4 or 5 computers earlier.

I have a fresh install of Maverick on a Toshiba r700 laptop PT310A-05N011. I am experiencing constant freezing. The computer will without warning completely freeze. Can not move the mouse or even drop to a tty shell. After about 5 seconds the fan will spin up to full speed. I then have to do a hard shutdown. Every time this has happened i have been connected up to a wireless network with firefox open while actively surfing the net. This issue did not happen before I installed the wireless driver (Broadcomm proprietary, downloaded through ubuntu Additional Drivers).
I'm not sure how relevant that is though as 90% of what i do on this laptop is surfing and i installed the driver a few hours after install. This freezing does not happen in windows 7 and I have left it running prime95 overnight once in both 7 and ubuntu without error. Does anyone know what this may be, how i might resolve it or steps I can take to diagnose it, logs i can check?

i ordered an AsuS Eee PC 1215T netbook off of Newegg:[URL].. i was confused and surprised to discover it didn't have an operating system, only the Express Gate Cloud. it was advertised as running on windows 7, but it's not installed. i called the ASUS tech support not once, but TWICE and they didn't know diddly squat. would anyone be able to walk me through how to install linux on it? the express cloud is a very basis system. there isn't a "my computer" function so i don't know how i would go about installing anything on it. from what i understand this little netbook has great potential, i just don't know how to harness it.

I've decided to move to Debian because I have noticed Ubuntu releases getting progressively more unstable.I am following the official Debian installation guide. Just did this with the Debian 6.0 Net install .iso: 4.3.1. Preparing a USB stick using a hybrid CD or DVD image. Debian CD and DVD images can now be written directly a USB stick, which is a very easy way to make a bootable USB stick. Simply choose a CD or DVD image that will fit on your USB stick. See Section 4.1,Official Debian GNU/Linux CD-ROM Sets to get a CD or DVD image.
Alternatively, for very small USB sticks, only a few megabytes in size, you can download the mini.iso image from the netboot directory (at the location mentioned in Section 4.2.1,Where to Find Installation Image).The CD or DVD image you choose should be written directly to the USB stick, overwriting its current contents.

I have a dual boot windows XP/ubuntu 9.10 set up on one hard drive. Everything was working fine. The 9.10 install had been updated from 9.04. I recently had problems with the XP partition (XP basically collapsed) so I re-installed XP on the same partition it was on before. I then attempted to reinstall Ubuntu ( I decided I wanted a new 'clean' installation of Ubuntu as well). When I got to the partition function it refused to recognize that there is a Windows partition, or a previous ubuntu partition, but states 'No operating system installed' or similar, and offers the entire hard drive for installation. When I look at the partitions using Windows partition software the Windows and the ubuntu partitions are clearly in evidence. I have also tried to reinstall GRUB but it doesn't appear to exist.
