Windows' Master Boot Record seems to be damaged on my dual-boot.Here are the details.
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> HP/Gateway is installed in the MBR of /dev/sda

I have a dual boot computer. The WindowsXP "side" has been infected with a rootkit virus. So far UBUNTU has not been affected to my knowledge. I have not yet been able to remove the virus from the WindowsXP "side". I am thinking of deleting the NTFS partition and have the computer fully dedicated to UBUNTU.
Now for my question. Is there a possibility that the virus resides in the MBR and that I need to "rebuild" the MBR to actually remove the virus? Even more extreme, should I totally re-install UBUNTU in the name of safety and precaution.
I think I managed to corrupt my master boot record, or have a very intractable problem with Grub.
I'm not sure how I did this, but my desktop will boot Ubuntu fine from a USB, but every time I try to install it, the install seems to go fine, but when I finish the install and the machine tries to boot the OS from it's hard drive, it does not work. The monitor does not get a signal and it just goes to sleep.
I tried posting here to resolve the problem before, tried everything on this thread: [URL]
But nothing worked.
I have even tried running the system from a USB, running a "shred" command for the hard drive and then reinstalling - my theory was that the shred command would destroy all the data on the hard drive anyway, and allow a "clean" install from whatever was corrupt on it, but no luck - when I installed Ubuntu on the hard drive, same problem.
I'm not clear where the problem lies now, I'm assuming there is something up with it's master boot record, but there are no partitions on it's hard drive and I started with a completely blank, unformatted drive.
I have a Windows XP/Windows 7 dual boot system. My problem: [URL]. I follow these instructions to the letter, the live "CD" works fine - using a USB stick, I do not have a DVD drive, in- or external -. When I try to install Ubuntu from the live system, it corrupts my master boot record, I get the Error: No Such Device #####################. After I fixed this I tried to install Ubuntu under windows, using the same usb's wubi installer. The install completes, I reboot, and after selecting Ubuntu in my boot menu, I get that likewise well known error with wubildr.mbr [URL]
Rebuilding the USB stick doesn't make any difference, it behaves the same way. The wubi installer has the very annoying habit of downloading the iso during the installation procedure every time, I don't know why I can't just select the iso downloaded in the first step of the above link. This way I cannot check any md5 because I have no idea where it downloads the iso. What should I do to get Ubuntu working? Reinstalling any of my Windows systems is not an option, it is every time like gambling, I am using the same installation files, but sometimes the result is just not the same.
I have a 1TB hard drive which is formatted with FAT32. Attempting to make a new partition I clicked the format drive button in Disc Utility. I chose Master Boot Record and something was written to the drive. So now I can't mount the drive and Disc Utility says that there aren't any partitions. I don't think this can be true because I had 200 GB of data on the drive and it would have taken longer to delete all that. At least I think...

Acronis Operating System Manager will let me boot into XP Pro but it tells me it cannot find SuSE in the master boot record. If I repair the master boot record in SuSE, XP Pro disappears. What do I do?

Then I could no longer log in to ubuntu, the partition table was some how courpt and I couldnt remount I then decided to use the windows partitioner from windows setup, as I thought it is so stupid, to reformat the partition where I had ubuntu. I wanted reinstall ubuntu, and I know that during the setup I could straighten out the mess I'd made.
Windows has now installed two 8mb one cylinder partitions on my HD. When I start the PC I get a !disk error occurred Press Crlt Alt Del to restart! This happens everytime. HD boot sequence is buggered, i guess.
I can boot from other devices. USB + CD. How when I use the windows disk to boot up I can see the 2 8mb partition, which it wont let me delete. How can I delete this via linux?
Also when I try to install ubuntu from the usb drive, it stalls just after the Preparing to install part. The next screen is when you set the partition table, swap drive etc. When I quit I get the following error !Process Glib WARNING getpuuid_r() failed due to unknown id!
The usb_liveCD does however mount my hard disk partitions and luckily I have managed to back everything up to an external.

I've been running a dual-boot ubuntu 11.04 64-bit and windows 7 64-bit for a while now, and recently got a new computer. I moved the hard drives to the new computer (one had both os's on it, the other was just a storage drive) and windows 7 would not boot, so I reinstalled it. I used a live cd to repair grub using boot repair /Boot-Repair) and everything looked to be going swell But when I tried to boot I got "invalid or damaged bootable partition" instead of a grub menu. so I went back and, copying and pasting the commands the program gave me, I manually removed and reinstalled grub on my ubuntu partition. same error. so, I backed up all my documents onto a third drive, wiped everything out, and started again. I installed win7 on one drive, and then when that was done, I installed ubuntu on the other. lo and behold when I tried to boot I got the same error message, and now I can't even boot from my windows drive. The ubuntu drive is fairly new and according to disk utility has no errors. Is this some problem with grub or what?

View 2 Replies View RelatedI have a new Dell Inspiron 1545 with a dual-boot setup: Kubuntu and Windows 7. A long, tedious story made short, I have Kubuntu working but cannot for the life of me get the wireless adapter to work in Windows 7. Since the Microsoft universal fix consists of reinstalling the OS, that's what I plan to do.
That said, I'm concerned that Windows will not just reinstall itself, but wipe out the boot record used by grub. I've invested enough time setting up Kubuntu that I really don't want to start from scratch (again) with both OSs.
How to reinstall Windows without wiping the boot record? If not (i.e. Windows will kill whatever grub has in place), is there a way to use the Kubuntu disc, or another linux disc, to reinstall grub afterward, thereby leaving the linux partitions intact?
I have a HDD with OS Win with three partitions NTFS.I installed Ubuntu 10.10 on new partition, and I left the old partitions on the disk, because there are a lot of my personal data.When I was looking for how to mount partitions on startup, I was fortuitously to Palimpsest Disk Utility selecting the checkbox on sda2 as a boot, and apply. But I saw that it was wrong and took the check back. And after this was damaged NTFS on the partition sda2. Windows shows the partition as RAW.

following problem. A friend phoned me in despair. Her Ubuntu didn't start any more - ASUS-Laptop switched on stops at a ramfs-prompt.
I started Puppy-Linux from DVD-Drive. Worked fine. But puppy can't mount her /dev/sda1 partition either. At least you can see that the partition is still there. Fsck stops with an error. May be the initial problem is a sort of bad hardware by which bad bytes were written to the hard drive. Hard drive and/or memory could be replaced but not the data.
Yesterday, my windows xp died and I can not do anything with that, but I would like to rescue my important files from hdd before format. I open ubuntu trial version from cd but i can not access my hdd. I find my hdd in system->administration->disk utility but I can not go anywhere from there.
When I solve this problem I would like to try ubuntu as my os but i am worried that some programs may not work on it . Like for example my bamboo tablet, fm2010, adobe ilustrator, autocad.
is it possible to use a Windows-based recovery partition on a dual-boot computer to overwrite the Ubuntu partition and remove the GRUB loader? For instance, if you booted up your computer, accessed the hidden recovery partition and used it to reset the computer to it's factory default settings, would that effectively remove the Ubuntu partition and the GRUB loader? Would a completely new installation of Windows overwrite/uninstall Ubuntu and GRUB automatically?

View 7 Replies View Relatedsome info on the drive - it's a USB 2.0 portable hard drive (PQI H560), one partition spanning all 640GB, NTFS. Used almost exclusively on Linux (arch and ubuntu), but initially formatted on Windows 7.The hard drive has quite a lot of hard links on it, as it was a timemachine-like backup system.And now the issue itself:Today I made the mistake of taking out my portable hard drive from my Linux system and plugging it in a Windows 7 box. Everything worked nice, I took a movie from the drive, and it lay dormant for an hour or so. After that I took the drive out (forgot to unmount :/) and put it back in my Linux.
Any idea why did it break so bad? I thought NTFS was kind of durable.Best if there would be something nondestructive (be able to get the data while preserving every bit of the drive in it's current state - just to be sure it doesn't break anything)
I'm using Karmic Koala 9.10 (amd64) on /dev/sdb6 and windows 7 on /dev/sda2. I mounted my windows 7 partition in Nautilus. I copied some files and made some folders from Nautilus onto my windows 7 partition. I tried booting into windows 7 but it failed on loading Windows 7. It then gave me a blue screen flashes and then restarted. The blue screen flashes so quickly i cannot determine the exact issue. I tried booting into windows 7 in Safe mode. It fails to load and gives what i believe is the same blue screen. I used to be able to read and write files onto my old XP and Vista partitions. Now with windows 7, I seems that I can't.

I'm managing a residential network. Each flat is its own subnet, and can only communicate with the other flats through a router (i.e. no broadcast). 95% of these 300 subnets only contains windows computers (from lambda users).
My final goal is to be able to browse the entire network from any computer.
I set up a samba server acting as a wins server, and every computer is aware of it because it is registered in the dhcp. So name resolution is working fine for everyone.
The same samba server is set to be the "Domain master browser":
workgroup = WORKGROUP
wins support = yes
prefered master = yes
local master = yes
domain master = yes
os level = 65
When I browse the network (using "net view" or "browstat view"), I can only see the servers which are in the same subnet as the domain master browser.
Now, when in a subnet the computers arrange themselves to find a "local master browser", the only visible computers are the one in that subnet.
What I don't understand is why all the local masters don't synchronize their lists with the domain master.
So, to sum up, every subnet get the following behaviour:
-if a local master is elected, the only visible computers are the one in the same subnet.
-if no local master is elected, the only visible computers are the one in the subnet of the domain master.
-if I add another samba, configured as a local master winning all elections, then the magic is working and the lists are synchronized.
What is expected:
-every computer can see all the computer from all the subnets.
Its basically an old SATA Hard Drive with a Windows XP partition I was trying to sell.When my computer does the BIOS checks, it doesn't pass the SMART test (but I can boot it anyway), although I can't boot Linux in any way with this Hard Disk connected (I even tried Live CD distros, like Parted Magic).I can boot the XP partition from inside the disk, although I guess its pretty close to not being able to. Is there any way to "fix" this Hard Drive?

I had a dual boot backtrack 5 with windows 7, I had no need for the backtrack partition anymore so i deleted the backtrack partition and extended the windows NTFS to take up all free space, now my computer boots to grub but it will not boot into windows. I am currently in the process of creating a ubuntu live cd to do the following to repair the windows Master boot record.

So Ubuntu needs to go so I booted onto a live CD of Ubuntu and used Gparted to delete every one of my linux partitions. I created a ntfs partition, will windows boot on this. When i tried it before it said didn't recognize file system so I deleted the linux file system and created a ntfs one. Is that all?

View 9 Replies View RelatedUpon trying to boot Windows I got through the GRUB startup selections and then i get stuck at a black screen displaying "Starting Up. . ." That would be no problem, I just boot ubuntu instead and mount the partition to access the programs I'm looking for. Now I get an interesting error message:
"Error mounting: mount exited with exit code 13: ntfs_mst_post_read_fixup: magic: 0x00150000 size: 4096 usa_ofs: 0 usa_count: 1040: Invalid argument Actual VCN (0x15000011d92501) of index buffer is different from expected VCN (0x1). Failed to mount '/dev/sda1': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details."
I would run chkdsk in windows if I could, but that's my problem in the first place.
After upgrade to Ubuntu 10.4 i can't boot windows partition. the only thing i get it's a blinking underscore after choosing it from grub. under ubuntu the window partition seams to be ok, and i can access every file.
this is my partition table:
sda1 - ntfs
sda2 - extended
sda5 - swap
sda6 - ext4 linux (0x83)
is there any tool to config grub? like yast on suse? (off the topic : is there any "grafic" version of grub?)
I'm running a dual boot of Ubuntu 9.10 and Windows 7. For months now everything has been just wonderful. Recently, however, I tried to add another partition (in windows) and saw that my Ubuntu partition is recognized as RAW. I formatted it as NTFS originally. In Ubuntu, it is recognized correctly (ext4). I don't know what's going on. I'd like to be able to install drivers to recognize this partition in Windows. Will I have to reformat? I'm not sure if it's at all connected, but probably worth mentioning: while booting into Ubuntu, I received an error about "usplash mode failed." It also said something about "mount of filesystem failed." (I really, really wished I had written down the error message.) Everything seems to work now.
