How to use Windows Vista’s Boot Manager to boot Linux
OpenHiddenSystemDrive
How to Open Windows 7 Hidden System Reserved Partition
BCDEdit (Befehlszeilenoptionen)
Mit bcdedit das Boot-Menü von Windows 7 konfigurieren

1. Create /boot Partition with EXT4, ex. /dev/sda9
2. Extract boot sector
   $ dd if=/dev/sda9 of=/tmp/linux_boot.bin bs=512 count=1
3. Copy 'linux_boot.bin' to USB-Stick
4. Boot Windows with F8-Key pressed
5. Go to the command-line
   bootrec.exe /fixboot
   bootrec.exe /fixmbr
6. Boot Windows normally
7. Find file 'bootmgr' in root directory of 'System Reserved' partition (OpenHiddenSystemDrive64.exe)
8. Copy 'linux_boot.bin' from USB-Stick to root directory beside 'bootmgr'
9. Start BCDEdit (An example of {LinuxID} is {81ed7925-47ee-11db-bd26-cbb4e160eb27})
   bcdedit /create /d “GRUB” /application BOOTSECTOR
   bcdedit /set {LinuxID} device boot
   bcdedit /set {LinuxID}  PATH \linux_boot.bin
   bcdedit /displayorder {LinuxID} /addlast
   bcdedit /timeout 10

“warning: File system `ext2′ doesn’t support embedding.” but my system isn’t embedded either, why is grub trying?
I need step by step guidence to recover grub [duplicate]

$ mount /dev/sda5 /mnt 
$ mount /dev/sda9 /mnt/boot 
$ mount -o bind /dev /mnt/dev 
$ mount -o bind /sys /mnt/sys 
$ mount -t proc /proc /mnt/proc 
$ chroot /mnt /bin/bash

# grub-install --force /dev/sda9
Installing for i386-pc platform.
grub-install: warning: File system `ext2' doesn't support embedding.
grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
Installation finished. No error reported.

$ dd if=/dev/sda9 of=/tmp/linux_boot.bin bs=512 count=1

You are getting the warning because you are installing grub to a partition instead of the MBR. This means grub can not be embedded in the unused space between the MBR and the first partition.

Writing a Simple Garbage Collector in C
Garbage Collection in C Programs, LISP and Java programmers take garbage collection for granted. With the Boehm-Demers-Weiser library, you easily can use it in C and C++ projects, too.

Is there any embeddable lisp or scheme?
ECL – Common Lisp language (look at the GC part!)

Stack-based:
alloca(): Automatic Storage with Variable Size

No, that would not be possible. The fundamental design choice for the BDW
GC is that it is "conservative": it does not know exactly which registers
and local variables contain pointers, so if it were to decide to move heap
objects around, it would have no way to safely patch up all pointers to the
moved objects. (Some of the words that look like pointers to a moved object
might actually be non-pointer data).

In general a collector that moves objects demands either deep integration
with the compiler's code generator (such that every stack frame is marked
up with exact where-are-the-pointers information), or very tight discipline
in the source code of the client program such that moveable pointers are never
stored in local variables across points calls the collector might run. The
latter is probably compatible with programmer sanity only for generated code
and/or when implementing a virtual machine.
