I've a Lenovo G50-80T with W8.1. I want to install Debian 8.1 in dualbooting mode. I've done this other times without problems. But this time I want encrypt the Linux partition (not the Windows partition). I'll use dm-crypt to do that. I want to know if this way is secure for protect the data on Linux partition or if I need encrypt the entire drive.
View 3 RepliesI have Windows 10 and Deb 8 dual boot, and I need to re-install Windows but want to avoid (or at least plan for) losing Grub/Linux boot.
Last time I re-installed Windows after Linux I ended up having to re-install Linux again afterwards as well, because I couldn't recover it (seemingly due to complications from encryption). So this time I'm wanting to plan and avoid that.
CURRENT DISK PARTITIONS:

As there is a "Microsoft Reserved" partition and a separate Microsoft directory within the EFI partition, if I just go ahead and reinstall Windows will it install it's boot loader/image to one of it's own partitions? And NOT affect anything else like Grub and other Linux things?
Logic tells me yes, but there seems to be many issues on the internet about installing Windows after Linux.
My primary concern is whatever happens with Windows or anything to do with dual loading etc, is that Linux will still just boot, or I can get it working again without much hassle.
Why is there a reserved Microsoft partition AND a Microsoft directory in the EFI partition? Which one boots Windows?
Why is there a separate Linux Boot partition AND a Linux directory in the EFI partition? Which one boots Linux? Where is Grub invoked from, is one redundant, etc?
How these work. It is possible I've set them up wrong, or with redundant partitions, but both systems have been booting ok for months.
I'm currently dual-booting Squeeze & Windows XP on a machine i use frequently.
In my experience on the desktop, i now see no reason to have Windows XP as a boot option, & wanted to try & avoid a full re-installation of Debian in order to remove XP (merging it's partition with / ).
I have a checklist that i put together, but wanted to be sure this was all correct before going forward.
1. Perform full back-up of all data.
2. Boot into Debian, through GUI -
System Tools > Disk Utility
- Select HDD (80GB Hard Disk)
- Select windows partition ( /dev/sda1 )
- Format /dev/sda1 to Ext4 Filsystem
3. Boot Live CD
- Use gParted to extend /dev/sda2 (was 38GB, will extend to 78GB)
4. Remove XP from the boot menu.
( Note: My ~ folder is on the same physical drive as / (same volume), but i actually store all Media on a separate physical drive which is formatted in NTFS. I plan on reinstalling XP using a virtual hard disk, & sharing that with the virtual machine.Here is a screenshot of my Disk Utility - [URL]
I've been wanting to do this for a while and after upgrading some of my pc components I decided I would finally try to dual boot with full disk encryption on both windows 7 and Ubuntu 9.10. I managed to encrypt the windows drive with truecrypt and that worked. I installed Ubuntu 9.10 using the alternate cd and everything but /boot is in an encrypted LVM. Each OS is on a separate SATA drive the windows is on sda1 and ubuntu /boot is sdb1.
To setup the dual boot I started out following the tutorial [url] but its for XP and versions of ubuntu that use grub not grub 2. I ran dd as posted and saved the files it produced from truecrypt. I then ran into some problems with grub reinstallation so I simply reinstalled Ubuntu 9.10 from scratch again. This put grub 2 on the computer. I've managed to get it to add a Windows 7 option.
However, when the option is selected truecrypt comes up and says that the bootloader is corrupted and that I need to use the repair CD I burned before I encrypted the drive. My question is does anyone have any experience dual booting using Truecrypt on Windows 7 and LUKS/dm-crypt on Ubuntu 9.10 with grub 2? And how would I get the boot menu to work? I'd rather not reinstall but if I have to I have images from right before I encrypted so it wouldn't be the end of the world.
I'm trying to get a dual boot system. And my situation is exactly as the situation described is this article:URL...

Is there a simple latex-compliant text editor (gedit or something else easy to learn) for linux that supports reading and writing MS Windows files? It the editor doesn't support it, I may choose to wrap the files in "unix2dos" or something.

Here are the boot informations:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks at sector 488861020
of the same hard drive for core.img, core.img is at this location on
/dev/sda and looks on partition #3 for (,gpt3)/grub.

I have a DELL Latitude E6410 64bit with Core i5. My goal is to have my Windows 7 encrypted and my Ubuntu 10.4 unencrypted and to be able to boot them both. So here are the details. I installed windows 7 first. Then I installed Ubuntu and Grub was in the MBR. Then I started TrueCrypt 5 from Windows 7 and encrypted the system partition, not the whole drive! So the TrueCrypt loader overwrote the GRUB in the MBR. Now when I start my computer, I see the prompt for password from the TrueCrypt boot loader. If I enter my password, windows is loaded.
The other option at the beginning is to press Esc and that should offer me other boot loaders. Well, on my DELL there's this Recovery partition and it boots immediately. How I can integrate the Grub in the process. I know, that there are many howto-s on the internet about this problem, but I haven't found a solution for grub2 and windows 7! It is indeed different, because GRUB does not have menu.lst any more and Windows 7 does not have boot.ini!
Here some more info about my partitions:
Code:
/dev/sda1 fat16 DellUtility
/dev/sda2 ntfs RECOVERY
/dev/sda3 unknown
/dev/sda4 extended
- /dev/sda5 ext4 ubuntu
- /dev/sda6 linux-swap
Windows 7 in installed on /dev/sda3 and is encrypted, that's why the file system is unknown.
Ubuntu 10.4 is installed on /dev/sda5
I know of three options to deal with the problem:
Solution 1
Install GRUB to the PBR (partition boot record) of the linux partition - that's /dev/sda5 in my case. Then, it should be possible to load GRUB when you press Esc in the TrueCrypt boot loader.
solution 2
Make Windows load Linux. Copy the PBR of the linux partiotion to a file and copy the file to windows. Then add an entry in the windows loader to include the linux loader file.
solution 3
Make GRUB load TrueCrypt's boot loader. Make a backup of the MBR (containing the TrueCrypt's loader). Add Truecrypt's MBR as a chain boot loader in GRUB. Finally, rewrite the MBR using this new GRUB.
I did install GRUB to my PBR with
Code:
from the live CD:
first mount /dev/sda5 to /media/ubuntu
sudo grub-install --root-directory=/media/ubuntu /dev/sda5
I also tried with
Code:
from inside ubuntu:
> grub
grub> find /boot/grub/stage1
hd0,4
grub> root (hd0,4)
grub> setup (hd0,4)
grub> quit
After one of these, I am able to boot my ubuntu after restart. But then I reboot and load windows, reboot once again and press Esc in order to try to boot ubuntu again, and then I don't see the grub loader list, but the "grub> " shell prompt instead! I thought that I will be able to see the grub loader also after many restarts, not just the first time. Why this configuration "breaks" after 1-2 reboots? Maybe the problem is that my ubuntu is on an extended partition (sda4)?
One of the things holding me back from building a new system with nothing but Linux is the vague possibility that that I might need to use some proprietary program that only works on Wind'ohs in the future. So far it has been easy to keep dual boot systems around, but a new system will be > 4 Gb of RAM of course, so I can't just install one of my copies of Win XP on it. But buying a new 64-bit version of Wind'ohs for ~$200 seems a waste.Is it now possible to run XP in a "virtual" machine under Debian? More importantly, is it possible to install XP completely from within the virtual machine so it never sees the > 4 Gb or RAM and freaks out? What sort of hardware is required to do something like this? I presume a CPU with certain special capabilities is essential, but wouldn't those special instructions (whatever they are) be pretty standard now? Would the virtual XP install need its own partition?
View 1 Replies View RelatedI have a Jessie with grub2. I've bought ssd and copied root partition onto it. I've also installed grub on this disc. I would like to have dual boot:
- First option: old root booted from hdd
- second option: boot from copied ssd and use root from it.
So i would have two identical but independent configurations.
Both disc has different uids (changed after cloning).
I had a hope that i will change fstab to mount root partition from ssd, but it doesn't work. I need to change grub configuration, but how to add new position?
There is also problem that bios doesn't allow me to choose disc to boot from. So i would rather prefer to change grub configuration for dual boot from different disc.
I'll start off with stating my problem and summarize how I got to it.
I installed Windows 10 on an SSD. I installed Debian 8.2 after it. The SSD was/is a GPT disk. I installed both installations from a UEFI booted device (DVD for Windows, and USB drive with Live CD for Debian).
I tested it after each installation making sure I could boot via UEFI into Windows, then Debian, then Windows, to make sure nothing broke.
I rebooted the machine. Suddenly, no more UEFI. Nothing. I didn't change any BIOS/UEFI setup menu settings. Not even my USB drive with Live CD will boot through UEFI anymore. Even when nothing else is plugged into the system.
My situation is actually a bit more complicated than that, but I think that will suffice for now. I can still boot into the Live CD on the USB drive, just in Legacy mode only. I mounted the EFI partition on /mnt/boot after I mounted the file system for Debian on /mnt. It is identical, as far as I can tell, to as it was before when it was working.
My motherboard has CSM and Secure Boot, both have been set up how they need to be to boot UEFI into Debian. Tinkering with them further after things broke did not fix it. I tried all variations of options/settings.
The GRUB Reinstall guide says to be in EFI mode before starting it, so I can't do that.
My motherboard is an ASUS X99 Deluxe, and I've heard ASUS has special "features" (read: bugs) that come with their boards. Searching hasn't brought up any other people with this issue. I believe the firmware is updated to it's most current one.
I've tried dd-ing my backup of my old system, from before trying to migrate to a Dual Boot system, to the SSD (after backing up the dual boot setup with dd -> <name>.img via the Live CD USB). However, that won't boot either as it is a UEFI install as well.
The layout of my EFI partition is as such:
/boot/EFI/Boot/bootx64.efi
/boot/EFI/Microsoft/<Microsoft-naming>.efi
/boot/EFI/debian/grubx64.efi
I've heard that the standards on how that's supposed to be set up isn't a standard. However, since it worked booting into the OS' the first time, I don't see how that could be the issue (a bad hierarchy layout leading to the UEFI not being able to see the OS installs).
I've seen that I can boot to an EFI shell (called Shell.efi, apparently) via an option in my UEFI BIOS setup menu on my motherboard. Is that an option here to somehow bypass this strange issue?
All I can think to try is burn it all and start over. But not knowing what caused it means I could just make it happen again. Plus, I can't boot into UEFI install media, so I can't install UEFI boot OS'. :/
I've recently bought a new computer and installed Windows 7 on it, but left 100GB of space on a separate partition so I could put Debian next to it in dual boot. I have the new Intel i7 950 processor and I run Windows 7 Proffesional 64 bit, so I assumed I had to pick the ia64 debian image. However the CD I burned from the ia64 image didn't boot. (a black screen started and an underscore kept flashing, but nothing else happened)[URL]
I've managed to install i386 Debian on a older intel pentium 4 computer before and that worked fine. I believe I used another application to burn the CD then. This time I've burned the CD with the default Windows CD burn application. I can try burn more CD's but I don't have much left so I want to make sure this is the problem before attempting again. (the burned files on the ia64 CD look exactly the same as the files on the i386 CD, when browsing through the cd files in windows) "If your PC has a 64-bit AMD or Intel processor, you will most likely need the "amd64" images (though "i386" is also fine), the "ia64" images will not work."This seems a bit strange, they recommend me to use the amd64 image if you have a "64-bit AMD or intel processor". I dunno if this is a typo, but it seems weird to me that the AMD-64 Debian version would also work on my Intel machine

I had to boot into my Windows 7 install on my laptop for the first time in a few months and I noticed that the Windows clock was 4 hours ahead.

View 6 Replies View RelatedI have a Dell laptop (inspiron 1150) which was dual booting Windows XP and Ubuntu 9.04. I have successfully installed Debian Jessie Standard over the Ubuntu. I pre-partitioned using gparted-live to make a separate single partition for the Debian install. Guided partitioning was then carried out by the installer producing separate /, /home, and swap partitions. After installation, the grub menu shows an entry for Debian and Windows XP. I can boot Debian, but not Windows XP. The symptoms are the same as reported in other forums: A terminal is displayed, vanishes and the system reboots defaulting to the Debian boot.
The grub.cfg file for the Jessie system has an other-os entry:
Code: Select allmenuentry "Microsoft Windows XP Home Edition (on /dev/sda2)" {
  set root=(hostdisk//dev/sda, msdos2)
  search --no-floppy --fs-uuid --set=root cc0ce0ab0ce091ae
  drivemap -s (hd0) ${root}
  chainloader +1
}
The original Windows entry for the Ubuntu install was:
Code: Select allmenuentry "Microsoft Windows XP Home Edition (on /dev/sda2)" {
  insmod ntfs
  set root=(hd0,2)
  search --no-floppy --fs-uuid --set cc0ce0ab0ce091ae
  drivemap -s (hd0) ${root}
  chainloader +1
}
The partitions produced by partman look OK (during the pre-partitioning I did not touch sda1, sda2, or sda3):
Code: Select all~ # fdisk -l
Disk /dev/sda: 37.3 GiB, 40007761920 bytes, 78140160 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
[Code] .....
Partition table entries are not in disk order.
The os-prober found XP:
Code: Select all~ # os-prober
/dev/sda2:Microsoft Windows XP Home Edition:Windows:chain
So it seems that everything is in place, but there are perhaps important differences in the grub.cfg files. Are the two "set root" commands equivalent for example?
I've been using Debian for a few years but always on dedicated boxes and/or VMs.
Finally decided to dual boot Debian and Windows on my main Desktop PC.
Installed as I normally would using, however this time using a seperate drive (one for the existing Windows 10 install and the other for Debian), Debian install detects that windows has an EFI partition and sticks an entry in there, which is fair enough, and everything working fine. Then I spent some time configuring all my software and set it all up just the way I like it. I've rebooted Debian a few times to check it's working correctly and it is.
The issue arrives when I reboot and load into Windows 10. It boots fine.
However after a further reboot GRUB no longer loads... and the machine just boots directly into Windows 10.
After doing some further digging into my EFI partition (and reinstalling various times) it would appear that after a reboot Windows 10 deletes the entry GRUB creates in my EFI partition after EVERY reboot.
Done some googling and most people advise turning off 'fast boot' in Windows as it locks certain partitions to facilitate the machine going into hibernation, only to find that it's always been turned off on my machine (I recall due to a driver issue with my graphics card this had to be turned off when I installed Windows 10).
I've found this article on the Ubuntu forums : [URL] .... however I've tried their steps and windows is still doing a hostile takeover of my EFI partion after a reboot!
Any way to stop Windows 10 from interfering with my EFI files after a reboot? (without doing the obvious thing and kill Windows off).
I have used dual boot systems using various versions of windows and Debian for many years and have encountered no problems. However, I have a problem with installing Debian on a EeePC (ASUS PC1201) which uses Winows 7.

/dev/sda1 ntfs 992.5 KB
/devf/sda2 ntfs 100.00 GB with 66.09GB unused
/dev/sda3 ntfs 132.88GB with 129.88 GB unused
unallocated 1.00 GB
Debian Squeeze (the net install version) will not install. G was the result of trying to provide some swap space. How do I prepare the hard drive so that Squeeze it will install on F: ?
how to install Debian after Windows is already installed. Could someone give me a brief guide to begin the process of installing Windows? When I installed Debian I already made a partition for windows (in the same hard disk), I hope I did it right.

there were no entries in the Grub 2 menu after booting. I don't really understand the numbering of hd0,0 to like sda, but I changed "root (hd1,0)" to "root (hd0,0)" if Windows is on hd0, but after rebooting, I still didn't see it. I read somewhere that Grub2 starts partitions at 1, but wasn't sure that was true because in menu.lst they start with 0 sometimes. know entry-level steps to solve this?
I upgraded a while back to Windows 7. I run two separate HDDs, with debian on sda and windows on sdb. Everything worked fine, up until i upgraded to windows 7. The installer forced me to unplug sda. After installing I repositioned the HDDs and was stuck with a "NTLDR is Missing" message. After removing the search -fs--uuid tag from grub.cfg, Windows 7 booted for a good 0.5 sec and then rebooted. All that flashed was the "Starting Windows" page. I see similar bugs reported in the launchpad, but nothing that directly parallels this.
Here's my windows entry in grub.cfg:
Changing ${root} to (hd1) makes no difference. Also, I've been using Windows 7 for moths now without a problem, it's only when I try and boot it form grub2 that I get a problem. Physically removing sda lets Windows 7 boot fine.
