I've currently installed Windows 7 and Ubuntu via dualboot. To avoid switching the OS by rebooting, i want to be able to start my Windows 7 via a virtual machine.
It is important to be able to boot Windows directly. Windows itself is configured via domain by my employer. However these restrictions (no port opening, no software installations, internet over proxy etc) make it far do difficult for my job as developer. (to avoid unnecessary discussions: there is no way to get any other configuration by the company. Tried everything, its simply a NO)
Now i installed Ubuntu which allows me to actually use my IDE, debug my code, compile my stuff, whatever.. Simply put: it allows me to work.
There is only a single problem: I cannot access my E-Mails, Calendar and Phone-System. These systems are configured to run only over a proxy which whitelists you as long as your Windows Domain Login is signed in.
So the general idea is to load up the Windows inside a virtual machine, to be able to use Outlook and the other applications. I do not need that much performance on the VM anyway.
I tried working with Virtualbox, but due to the fact the BIOS is locked, VT features are disabled in the bios, and the Windows install is a 64bit Installation, i have decided to use qemu.
I came across this article: http://fds-team.de/cms/articles/2013-12/use-a-real-windows-7-partition-in-virtualbox-kvm-vmware-player-u.html which i am trying to follow currently.
I've read the whole article, but i get stuck pretty quickly. When creating the linear raid, i get /dev/md0 which is exactly 43 sectors smaller than it should be. Now i am afraid of progressing further, as destroying the Windows installation has to be avoided at all cost.
This is my disk partition table:
Disk /dev/sda: 111,8 GiB, 120034123776 bytes, 234441648 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x8c663b07 Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 1023999 1021952 499M 7 HPFS/NTFS/exFAT /dev/sda2 1024000 118211499 117187500 55,9G 7 HPFS/NTFS/exFAT /dev/sda3 118212606 234440703 116228098 55,4G 5 Extended /dev/sda5 118212608 217847807 99635200 47,5G 83 Linux /dev/sda6 217849856 234440703 16590848 7,9G 82 Linux swap / Solaris
And this is the md0 device:
Disk /dev/md0: 56,4 GiB, 60524265472 bytes, 118211456 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xd765df67
What is causing this mismatch? Is there any way i can fix this, or is there any other approach to boot my local installed Windows 7 into Ubuntu? Is there a risk my Windows partition gets destroyed if i proceed to create the partition table on the md0 device?
Any help would be appreciated
