Ubuntu hangs at Loading initial ramdisk after grsecurity kernel patch
I am trying to patch my Ubuntu version with grsecurity.
I'm working with Ubuntu Server 12 32bit inside a Windows 7 virtual machine.
Windows 7 is running VirtualBox.
For patching I used the official tutorial of grsecurity wikibooks.
This means that I downloaded the right version of the Linux kernel and patched it with the latest version of grsecurity.
Then I installed the kernel by issuing the following command:
make-kpkg clean fakeroot make-kpkg --initrd --append-to-version=-grsecurity kernel_image kernel_headers
Also I can't use recovery mode anymore, because I am unable to select anything.
The ‘[[B’ character sequence appears when I press the down button.
I really have no clue what to do.
I googled around a lot for the error but I couldn't find a working solution.
Some information about my system:
lspci 00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02) 00:01.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II] 00:01.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01) 00:02.0 VGA compatible controller: InnoTek Systemberatung GmbH VirtualBox Graphics Adapter 00:03.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02) 00:04.0 System peripheral: InnoTek Systemberatung GmbH VirtualBox Guest Service 00:05.0 Multimedia audio controller: Intel Corporation 82801AA AC'97 Audio Controller (rev 01) 00:06.0 USB controller: Apple Inc.

If you need more information please tell me, I am out of options.
I know my way around Linux, but I wouldn't call myself an advanced user.
