Ubuntu :: 10.04 - No Dual Boot Option For Both Partitions
Jul 3, 2010
I was running Ubuntu 10.04 as my only OS. I then booted from the Ubuntu CD and divided my HD into two partitions, one for my Ubuntu and the other I formatted to NTFS so I could load Windows. I booted from the Windows CD and installed Windows on the second partition. I am now unable to boot into Ubuntu and I do not have a boot menu at start-up to choose what OS I want. I went back in with my Ubuntu CD and selected the "bootable" option for both partitions through Disk Utility but it still boots only to Windows. If I change the Linux partition to "bootable" and deselect that option from the NTFS partition, my computer starts up and then give the error, "No operating system present." What do I have to do in order to have a boot menu show up that will allow me to choose what OS to use at start-up?

I'm trying to install Ubuntu as a dualboot, i also have Windows XP. But during the installation, when this screen should appear
(Translation)
(*) Dualboot, choose at startup
( ) Empty and use complete harddisk
( ) Use biggest connected space
( ) Manually adjust partitions.
I get a screen with only 2 options, the second and forth. How do I get the Dualboot option?

have just installed Ubuntu alongside Windows 7. I just went along with the manual set-up all through the install. I was expecting to see an obvious option on starting up my computer as to whether to run Ubuntu or Windows but it just goes right ahead and runs windows exactly as it did before the install.

I am running Ubuntu 9.10 dual boot with Windows XP, on my 120GB hard drive I currently have the following partitions
a) 42GB - with WindowsXP installed
b) 10GB - for WindowsXP storage
c) 3.1GB - accidentally made when installing Ubuntu
d) 62GB - With Ubuntu installed
e) 2.7GB - swap space for ubuntu
I very rarely use WinXP and have nothing on b or c, so my question is can I get rid of those partitions to make d 75GB total without having to reinstall Ubuntu?

My brother installed ubuntu earlier this year, ended up not liking it, and somehow managed to delete all the Ubuntu folders from Windows XP without deleting neither the partition nor GRUB (which is what I'm assuming is keeping up the dual boot screens).
Info:
Dual boot - windows xp (SP3) and ubuntu
Laptop - Dell Vostro 1510
How do I get rid of the dual boot screen? AND how do I get rid of the partitions? I already tried to run Mbr fixer, but it hasn't worked. When I boot from the Windows XP CD I have, the recovery console doesn't detect the hard drive and therefore can't repair windows. I have the latest version of Kubuntu on hand - will installing this alongside or inside Windows XP wipe out the Ubuntu partitions or will it just create more partitions in the disk?

No option to install alongside another OS. I have Win7 Starter on this new netbook and need to install Ubuntu 10.10 netbook addition. Disk Management shows 4 partitions, one is C:, one is D:, and two I've never seen before they're so small. Is it safe to delete these or do they have a purpose for the current Win OS? I would gladly install the 10.10 to my D: drive which seems to be SDA2, the 131GB partition. What's the right sequence of partitioning and formatting to give Ubuntu the full install it needs manually? And what needs to be taken care of for a Swap drive?

Here's the short version of what happened
--Had windows 7 and installed Ubuntu dual boot
--all was well but after some messing around with a failed Backtrack install I had to repartition some things to clean it up
--The partition where Backtrack was installed was corrupt so I deleted it and extended my Ubuntu partition.
--reload got the no such partition rescue grub
--read threw a bunch of forums and could only seem to find mostly threads on only being able to load Ubuntu and not Windows. Most having to do with post OS install problems and not re partitioning.
--I decided the best thread to follow was [url]
--after that my memory of events is a bit fuzzy, a lot was going on. In short I got a message in the terminal saying "this is a BAD idea" and something about another MBR. (sorry I cant be more specific)
--reading on I decided I would try my windows bootloader restore
--now windows loads up fine but it doesn't even give me an option to boot Ubuntu. I launched a live CD and checked GParted. The partition is still there.
Sorry if this is threaded somewhere already, I know that annoying. I'm just burnt out on combing forums and broke down and decided to ask directly

I want to install Ubunto netbook on my compaq mini 730, but I want to keep my windows xp OS as well and have the dual boot option. At the moment I have the hard drive partitioned to C and D. My question is - what is the best way to install ubuntu and keep windows ? Should I create a separate partition for it ? if yes what size ? Can Ubunto install itself on C next to windows automatically ?

Slackware 13.0 32-bit is installed on /dev/sda5 with lilo written to that partition. Everything works and I have a nice lilo boot menu (for a WinXP bootable partion). Recently I installed Slack 13.0 64-bit on /dev/sdb5. This also succeeded (apparently). After reboot I was presented with my old boot menu, selected the 32-bit Linux option (/dev/sda5) and after login went to /etc/lilo.conf where I entered a boot stanza for /dev/sdb5 (64-bit linux), and then ran /sbin/lilo. No errors flagged. After reboot there was a 64-bit entry in the boot menu, but when selected it led to kernel panic. Further although I can mount /dev/sdb5 from the 32-bit partition there is nothing in it except lost+found.
So the current position is that I can't access my 64-bit linux partition (/dev/sdb5) to change anything in it (even boot: root=/dev/sdb5 at the boot prompt doesn't seem to work).how do I obtain access to /dev/sdb5? Second question is what items do I need in the 32-bit lilo.conf boot stanza so as to be able to boot to that 64 linux partition?
PS: OK I noticed one warning when I ran lilo.....
bash-3.1# lilo
Warning: LBA32 addressing assumed
Added Slack *
Added Slack64
[code]....
Maybe the problem is with the 32-bit addressing? How do I get lilo to use LBA32 for the 32-bit partition (/dev/sda5) and LBA64 addressing for the 64-bit partition (/dev/sdb5)?

I have a dual boot system 9.10 and XP. The hard drive is 234. For some reason during the install I only allocated 128 to windows and 16 to ubuntu. Or at least, gparted tells me I have 127.99 NTFS and 104 unallocated (=231G ??).
System monitor tells me I have the following:
/dev/loop0 is ext4 = 16 G total
/dec/sda1 is host = 128 G total
this is 134G total
From windows, the partitioner tells me the same. I have 104 of unallocated disk space and 128 of NTFS. I assume the 16G allocated to ubuntu is inside the 128G?. How do I get that additional 104 into ubuntu without screwing up the MFT of windows. Or can I? Is it as simple as telling gparted to format the space? or will that mess windows up?

So I wanted to dual boot Ubuntu with Windows 7, but have no idea how to partition out Ubuntu. At the moment, I'm working with a 300GB harddrive that will solely hold installed applications and stuff like that. Any shared/storage data will be put on separate harddrives altogether.
I plan on using a 40-50GB partition for Windows 7 alone (no installed applications and stuff). And here come the questions about Ubuntu partitioning. From what I read, do I only need three separate partitions? (/, /home, /swap) Even then I'm not 100% sure what each of these partitions represent. But my research says... / = equivalent to my Windows 7 partition, /home = the partition where installed applications go and other non-essential Ubuntu stuff, /swap = virtual memory
With all that said, to comfortably run Ubuntu can I have my partitions be these sizes?
/ = 10GB
/home = 20-30GB
/swap = 2GB (Do I even need this if I have 2GB of ram?)
Windows 7 = 40-50GB
W7 Apps = remaining space
I don't know what exactly I want to do with Ubuntu, but is a /home of 20-30GB adequate to install lot's and lot's of apps?

Setting up an old machine for some family members that are not so tech savvy. It will dual boot Windows XP and Ubuntu 10.04. The partitioning is as follows:
sda1 12 Gb ntfs WinXP
sda2 ----- ---- Extended
sda3 10 Gb ext4 Ubuntu

I'm setting up a new Dell as dual boot. I'm leaning toward first partition for Windows 7, a second partition that can be accessed from either OS, and an extended partition that will have root, swap, /home, etc. For the partition to be accessible to both, what is the preferred format? I've read that FAT32 or NTFS will suffice. ext4 is what I understand should be set for the linux partitions. For the linux partitions, is there an advantage to setting one or two of the partitions as primary, rather than logical? Also, any clear advantages or disadvantages to having a /boot partition? It is likely I'll only have installed one version of Ubuntu at a time.

I'd like to dual-boot it with Windows 7, but I'm not sure exactly how I should set things up. Searching has helped but I would really appreciate advice specific to my scenario. Windows 7 to run a couple games (mainly Starcraft II) and for anything that doesn't run on mac or linux, and Ubuntu to do most of my normal everyday stuff (documents, programming projects, web browsing, listening to music).Hardware: 1TB hard drive, 4GB RAM, AMD Athlon II 435 processor.

I am running a dual boot with XP and Ubuntu - what I want to do is increase the partition size of Ubuntu and reduce XP. When I run " G Parted" it shows both partitions with Xp being NTFS. I guess the boot loader is Grub because Ubuntu takes priority at Boot. I cannot persuade G Parted to allow me to resize the two different partitions. I am using the G Parted Live CD.

I would like to install Ubuntu in a separate partition. I currently have Windows XP on the C drive.
I have the following config on my Presario Laptop:
60gb SATA hard drive
41.6gb available
3% fragmented
I would like to partition the hard drive to install Ubuntu as a dual boot. how I need to do this or point me in the right direction? I did begin an install from a cd I burned from ISO. I started by just going for the auto installation and what it recommended. However, when I tried to install, I got an error message that changes were uable to be written to disk and had to abort??
Assuming I can get past the error I would like to know how to create the partitions for root, home and swap and how much space for each.

I installed fedora aside of windows 7 home premium 64 so I can choose which one to star. But its always fedora I set bios to boot from the cd drive and yes it ask me hit any key to boot from the cd so I can reinstall windows 7 but it's fedora again. It happens the same with the USB drive. I think I don't need to reinstall Win7, it's there in Hard Disk. I am new in Fedora (infact I installed Fedora today in the morning).

I've installed Windows 7 Ultimate on a notebook which previously ran Vista. No problems there.I've now installed Ubuntu (now updated to 10.04)so that it can boot to either OS.
It all works fine and when I first power up, I get a screen which invites me to select the OS I want to use. There are however two problems:
1) it defaults to Ubuntu (whereas I would prefer it to default to Windows 7 (it's a work laptop and most of the applications are Windows-specific),
2) the list of choices is getting increasingly complex with an expanding list of choices (with each major update of Ubuntu adding more); it even seems to include an option to go back to Vista!As long as I move down the list and make the right selection quite speedily, I get to where I want to be (though, as I say, I would like to change the default option).Is there any way I can edit/shorten this list without damaging the functionality and how can I change that default?

I've installed Lubuntu alongside my existing Windows XP installation. The menu came up on boot allowing me to boot into either Lubuntu or XP. But, after I install all the Lubuntu updates and restart, the option to boot into XP is gone. The boot menu comes up, but no XP option. I reinstalled Lubuntu again with the same results: after the updates, no XP option. I'm thinking I will reinstall Lubuntu again, and before I run the updates, I will make a copy of grub.cfg for later reference so I can add the XP section in again- am I on the right track here?

I have a fubar'd Windows 7 install I need to get working on another partition so I can do some development stuff. I use Ubuntu 95% of the time though and so the machine has an option at boot for what OS I want to go into. Does anyone know if I boot up with the Windows disc in and choose the repair option if it will screw up my boot options and I potentially lose my ability to boot into Ubuntu?

Basically what it says in the subject. In the Allocate Drive Space part of installation theres 'replace Windows 7 with Ubuntu' and 'Something else' but nothing for installing them alongside each other, which I want to do.

I am editing this post to save people time and effort. This is one of those "Pilot Error" issues or faulty readout issue, not sure which. It turns out that when I saved a document in PDF format to my NTFS Drive (the one I want to share between Windows XP and Ubuntu 10) the .PDF file extension was missing.
1. Ubuntu identified the files as a PDF document (even though the file extension was not there)
2. When trying to access it by double clicking it, the message was "Unable to open document, Permission Denied"
The problem was not permissions, and it was not a PDF file according to the default Document Viewer, but it WAS a PDF file according to the directory listing. The permissions message really had nothing to do with the problem, and identifying the file as a PDF document when it didn't have an extension, was another problem. What SHOULD have happened is a file without an extension should not be identified as a PDF file or If Ubuntu says it's a PDF file, and I double click it, why is the message "Permission Denied" ?? How about "No File Extension" or something like that?
Read the following if you want to see what my problem WAS before I just appended ,PDF to the filename, and now it works fine. On the positive side, installing XP first, then setting aside a large chunk of space for a shared NTFS drive, and THEN installing Ubuntu in the free space works fine. I installed a new 320 GB drive on laptop. Installed Win XP in 32 GB Set aside 250 GB for another Windows partition using MANAGE and formatted D: as an NTFS drive Then successfully Installed ubuntu 10 into remaining unused space. Problem: Ubuntu cannot access files from D: (NTFS Windows) partition. but it can WRITE files without problems, and create directories, just not read them. Have set properties of the Windows drive to shared, still nada. Any trick I'm missing? If I plug in an external USB drive, Ubuntu can read/write to it easily, it just can't read from the 250 GB partition formatted in Windows XP that I wanted to share between operating systems.

I would like to install Ubuntu on an HP Laptop, but they have taken up the whole disk with 4 partitions. I have removed Linux partitions and made an extended one in it's place creating new UUIDs before, but i am worried that windows will not recognize the new partition.

I'm completely new to Ubuntu, and haven't actually installed it yet, so my questions aren't concerned about how I use it, but rather the problems of installment and more importantly how to get started. The first thing I got a little question for is how to split my HDD into two partitions in order to install Ubuntu, as I will be dual-booting it with Windows 7. The second thing I want to ask about is how big the risk of corrupting my HDD is when installing Ubuntu, and whether I can take some precautions in order to reduce the risk of said thing. The third thing I'm gonna ask about is how to get drivers for my graphics and that alike. And fourth and last: Is it going to make a difference that I'm running it on a laptop?

However on reboot, I wasnt presented when boot option ( windows xp vs debian) but my windows xp directly got booted. How to get this boot option.

I have a Centos 5.5 system that had 2 primary partitions (2nd is setup as LVM with multiple LVM partitions) and then installed Windows 7 as Dual Boot.
However, Windows 7 has installed a 200MB system partition which is GPT/EFI as partition 3 and the Win7 OS as a Primary Partition.
I have a heap of space undefined after this fourth primary partition.
However, as 4 primary partitions have been used, I can no longer create an extended partition to utilise this.
As such I would like to know what is the best and safest way to proceed, and if possible step by steps instructions for the best option eg:
1. Delete the Windows 7 System Partition and create the extended partition (I expect this will prevent Windows from booting)
2. Use something like partition magic to change the Win 7 OS Partition 4 to an extended partition (Not sure if this will work)
3. Make changes to the overall system including both Linux and Windows so that it will use GPT only (I have
had no experience with GPT so this is a bit scary)
4. Other?

i'm trying to install 98se to a 110gb partition so i can dual boot with ubuntu 10 for 98 and 100 for ubuntu after the resize. when i tried making multiple partitions manually for ubutnu putting it on separate partitions i got grub boot errors. the problem i am having every time i try to install 98 it forces me to scandisk it then i have to hit space bar to fix every error i thinks it finds wich is impossible to press it 2 million times. now if I format in a non 98 format and tell it to format in lba it keeps asking for a boot disc, i burned one off but, still kept asking for it. if i do it in non lba, it only saw 2 gigs in 98 and when i went to install ubuntu it was a giant hard drive no partitions. i did try making 3 fat 32s 1 for 98 and then swap and linux partition but, the i got grub errors 17 and 18.
the problem is that bios a cap of 130gb for each drive or in this case partition. it's 320gb WD blue Scorpio. the short i want to dual boot 98se and ubuntu 9.04 with 2 fat32 partitions for storage 110 +100 + 80 = 320 also some visuals.
