Ubuntu Installation :: Does Not Detect Partitions Or Windows
Feb 11, 2010
I've installed the last year ubuntu 8.10 on dual boot with winodows XP, but then I had to format the XP so I lost the dual boot and access to ubuntu and I used only XP...Now, I downloaded Xubuntu 9.10, when I was trying to install it, when preparing the disks a message tell me that the PC has no operating system, then when I choose to manually partion the disk, xubuntu does not read the different partition I'm having and just display the hole disk as free space

Xubuntu 9.04 installation CD not detecting any of the current partitions. This all started when I reinstalled windows XP a few days ago.After, the computer wouldn't boot into GRUB and would boot directly into windows.Other threads have dealt with a similar issue, that of overlapping partitions causing libparted/parted/gparted to detect the whole drive as unallocated space. The problem in these threads seemed to be a corrupted partition table, in which the partitions overlapped with each other. So of course I checked the output of fdisk -l for overlapping partitions, but I don't see any obvious overlapping partitions. I've noticed that the partition that used to be linux swap isn't showing up in the partition table at all. I might just be missing something simple here and would like another set of eyes to help me figure this one out. Does the problem have anything to do with the partition table being out of order (ie. not in order of what regions they cover on the drive)? From the liveCD I've run
Code:
sudo fdisk -lu
sudo sfdisk -d
sudo parted /dev/sda print
and have received the following output:
Code:
ubuntu@ubuntu:/mnt$ sudo fdisk -lu
omitting empty partition (5)
Disk /dev/sda: 60.0 GB, 60011642880 bytes

I installed Windows 7, shredded the main partition for about 40 gigs (I made them unallocated), rebooted, Win7 works perfectly. THEN I tried booting Linux from a Live usb, and it doesn't recognize any partitions, it sees the whole HDD as unallocated space. This is the result of "sudo fdisk -l" done from the Live session: (I just copied the HDD info, not the usb)
Disk /dev/sda: 320.1 GB, 320072933376 bytes

I am installing Ubuntu on the same hard drive as Windows 7. The partitions of Windows 7 have already occupied the left part of the hard drive. From left to right, the Windows partitions are one partition for Windows booting, one for Windows OS and software installation, and one for data which is planned to mount on Ubuntu. I was wondering how to arrange the order of partitions of root, home and swap, i.e. which is on the left just besides one Windows partition, which is in the middle and which is on the far right?

I downloaded this "debian-6.0.1a-amd64-netinst" iso image....But on the partitioning screen, after selecting the manual partitioning, it shows the whole hard disk without detecting the XP partitions.

I'd like to have a dual-boot system with WIN7 and Ubuntu. I already have Windows 7 installed. I tried the 9.10 installation but the partitioner says i don't have any Operating Systems installed. I read a few threads about this type of issue and i didn't find any solution. Then i found a discussion saying that there is a problem with GRUB2 in 9.10 and that the problem is not present in 9.04. Then i tried the installation with 9.04 but got exactly the same problem: the partitioner does not detect Windows 7. Basically i have this system:
- Windows 7 Professional x64
- 1 TB HDD with 4 partitions with 100Gb each (NTFS)
- ~600 GB unpartitioned free space
- Processor Intel Core 2 Quad Q8200
- ASUS P5Q MOBO
- ATI Radeon HD 4550
I tried both the x32 (i386) and x64 (AMD) versions of 9.10 and the x64 version of 9.04. I don't have the WIN7 partition that some installations seem to have, at least i don't see it under Disk Management (Computer Management).

I installed maverick meerkat but for some reason there was no install to free space option so I installed onto 32gb of my 170gb windows vista installation. I NEED THAT INSTALLATION. Maverick Meerkat cannot detect my windows installation!

i did a fresh install of 10.04 on my asus 1005ha netbook (first-gen 1005ha, if it matters), and it works great. However, grub does NOT detect my windows partition. In gparted, the partition is recognized as "unknown". I can't mount it in ubuntu.
This is what fdisk gives me:
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

My windows 7 is not corrupted. it is also not virus-infected. I know what i am doing, and i know my windows is fine. it has been running fine prior to installing ubuntu. I'm just saying this becuz i noticed that viruses are a common response to similar problems like this.

I am running Windows XP Pro SP3 and it is currently setup on a system running 2 SCSI drives with an adaptec 2940 UW (non RAID) PCI card both are 18.4 GB. Windows XP is installed on the first one and I am trying to install Ubuntu 11.04 onto the second, but the installation doesn't recognize that windows is installed on the first drive and only gives me that drive as an option to install... Gparted recognizes both, one as an NTFS file system (sdb) and the second as a unpartitioned drive (sdc) and for some reason is placing the usb drive as sda which i'm assuming might cause some issues with grub boot loader later on after the drive is removed. what might be causing this issue and how i would go about fixing it... should i just go to 10.04 and upgrade to 11.04 after?

I'm trying to install Ubuntu 11.04 alongside Windows 7, but when I boot from the CD, Ubuntu refuses to detect the presence of Windows 7. I tried unplugging all my external hard drives to see if that made a difference, but Ubuntu still can't tell that I have Windows 7 on there.

I have a little problem. As soon as I boot my computer, Grub gives me an error 17. It happened after I tried to resize my Windows partition with a program. I have a dual boot between Windows 7 and Ubuntu 9.04.I've tried everything I could find on this forum and on the rest of the internet, but nothing was working. Most of them require a Windows CD (god knows where it is) or reinstalling grub and all that stuff, but it's all not working.I'm currently on a Ubuntu Live CD. Gparted doesn't detect any of my partitions, but just says 232 GB unallocated space. Palimpsest Disk Utility and the Explorer see all my partitions though EXCEPT my Windows 7 partition I tried to resize.

I want to install Linux Mint, but it cannot detect my existing partitions.I have a 500GB HDD, splitted in three partitions, on c: having a Win7 installed, and on d: and e: a lot of personal data.I tried to install Linux Mint, but the installer says there is no other OS installed and there is no any partition at all. I run the Linux Mint in live mode, Gparted says: "unallocated 465.76GiB". But when I go to Menu -> Computer then I can see each and every partition, I can mount them and browse them properly.I tried Ubuntu 10.04 and 10.10 with the same result as described above.

I have been trying to put windows onto my system as I made the switch to full linux awhile ago, but the need for certain windows programs is obviously tough to break.

I am posting this information because in the other topics I have seen they always asked for them. Whenever I use Gparted though there are no options for me to make a new partition all the options are basically greyed out and I have even tried using it from gksudo. I am on an EEEpc and cant really do much from the way of live cd's as I have seen in other topics as well.

I have a Windows XP system, and wanted to install Ubuntu to a 100 GB XT3 partition on the same drive. I was told I could chainload Ubuntu from the NT Loader menu. I booted from a Ubuntu 10.04 CD and ran the installer. It didn't find any hard drives. On a hunch, I tried the 10.04 alternate installer CD. That DID find the hard drive and partitions. I had the installer make /dev/sda7 (the XT3 partition) the root. Installation proceeded smoothly, but then the installer told me it did not see any other OS's on my drive! Why? I directed the installer to place grub on /dev/sda7 instead of the MBR.
Per the instructions I was given, I used DD to copy the first 512 bytes of /dev/sda7 to the Windows primary partition (sda1) as bootloader.lnx. But the resulting file is empty, and it won't boot. I repeated the whole process - formatting, installing FOUR times, and same results. I have no idea where GRUB was installed. It is apparently not in the MBR, because I still have my normal Windows boot. I downloaded the 10.10 alternate installer and got the same exact results. Even switched from XT3 to XT4. After two weeks of this nonsense, I still have yet to see Linux boot.

I will be getting a new computer soon, and I would like to transfer Wubi partitions from one computer with Windows to another. (The reason I want to transfer the partitions instead of just making a new installation is because I want to keep EVERYTHING intact and all the files/settings/applications/etc the same.)

I upgraded from 9.10 to 10.04 (no fresh install, an upgrade). During the upgrade, the installer asked me for the harddisks and partitions to include. I gave him the following ones:
Harddisk 1
1. Windows XP
2. Windows 2000
Harddisk 2
3. Ubuntu 10.04
After the installation was complete, I could only start Ubuntu. Both Windows versions just showed a flashing cursor at the left upper top screen. No HDD activity! How can I get WinXP and Win2000 selectable within grub2?

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'm trying to install Ubuntu 9.10. When it got to the "partition manager" stage of the installation, not only was I not able to decrease the Windows partition's size, I was also told that there was an error when partitioning and that the process has been aborted, I'm now just using the Ubuntu Live CD..

I'm trying to install Ubuntu 10.10 64-bit on my laptop HP pavilion 3046ee . When I reach the partition part , it doesn't detect the Windows 7 os , and doesn't detect any hard disk partitions ( it sees the whole hard disk as one unallocated partition ). I faced the same problem when I tried Ubuntu 10.04 LTS.

I want to install Ubuntu 10.10 on the hard disk, but the partition table looks a lot different than in Windows. I have uploaded two screenshots, one of the Disk Management from Windows ( http://oi56.tinypic.com/15y9bgw.jpg ) and another one of GParted ( [URL].... ). Also, I can't mount any of the partitions.

Ubuntu in Windows 7 (64 bits) File system installed using Wubi I got Ubuntu 10.04 LTS intalled using Wubi. That means Ubuntu resides inside Windows file / folder system. It also means Ubuntu does not have its own partition. Here is what I found out:
1) It cannot detect wireless network unlike Win 7 on this same laptop. However, when I plug in ethernet cable, it was able to detect it. Is there a fix this problem?
2) I cannot see Windows folders. How do access windows folder from Ubuntu side and vice versa?
3) I forgot to set the disk space for Ubuntu during install and I think the default is 17 GB.Would this cause me problems? If so, what do I need to do? How do I expand the disk space for Ubuntu?

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.

[URL](where loading into Windows corrupts the MBR). None of the solutions in the bug thread work for me, however--I'm on a Dell system (so it's not HP tools) and I'm not running PC Angel or any similar service (I checked). I assume it is related to the Dell recovery partition, though my old laptop from Dell didn't have this problem even though it also had a recovery partition.
However, before I had partitioned and set up Ubuntu on my new laptop, I installed Wubi (for transferring over the files from my old laptop because I didn't have time to do a full install and deal with problems like this one). Wubi worked fine using the Windows Boot Loader. I understand that WBL isn't capable of loading Linux on its own, which is why I was wondering if it was possible to have GRUB installed on a separate boot partition (not the MBR) and loaded from Windows Boot Loader. All of the information I could find on it didn't work with Windows 7--but again, I know Wubi was capable of doing it. how to set this configuration up?

I played a bit with partitions. I'm not an experienced Ubuntu user, neither I have solid understanding of partitioning. And I hardly remember exact actions that led to this problem. I remember that I saw a warning in GParted that said that the partition was out of bounds or something.. But I followed some solution that I found on ubuntuforums and used fdisk to fix that. So, after installation of Ubuntu I couldn't boot into WindowsXP (after choosing Windows entry in grub2 menu I see only blinking cursor on black screen). But what's more important that I can easily mount Windows partition from Ubuntu. Also I tried to boot from Windows repair console and used FIXBOOT command, and copied[url].... and [url].... files to no avail..Here is the summary of what I got now:
Code:
sudo fdisk -l
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders[code].....
