About the 64-bit Windows&linux dual system boot problem

Changed the Taiwan Book Win7 64, take the time to make a dual system, installed under Linux.

Encounter boot problem: Into the Linux can be normal use, into the Win7 flower screen, the initial estimate is grub (boot sector bit grub) problem, the initiator is destroyed a performance.

The corresponding processing is done as follows:

1, modify the/boot/grub/gurb.cfg under Linux, put:

1# # begin/etc/grub.d/30_os-Prober # # #2Menuentry'Windows 7 (loader) (ON/DEV/SDA1)'--class windows--class os $menuentry _id_option'osprober-chain-04ec18f4ec18e22a' {3        InsmodPart_msdos4         InsmodNTFS5Set root='HD0,MSDOS1'6         if[x$feature_platform_search_hint = xy]; Then7Search--no-floppy--fs-uuid--set=root--hint-bios=hd0,msdos1--hint-efi=hd0,msdos1--hint-baremetal=ahci0,msdos1 04ec18f4ec18e22a8        Else9Search--no-floppy--fs-uuid--set=Root 04ec18f4ec18e22aTen         fi OneParttool ${root} hidden- AChainloader +1 -  } - ... the } -# # # End/etc/grub.d/30_os-prober # #

Modified to:

1 1 fi

2 Parttool ${root} hidden-

3 ntldr/bootmgr # # # BOOTMGR Launcher # # #

Reposition the start position.

then re-install grub,quote online case:

Make a update-grub in bash beforehand.

Can get

The drive location of the win system

For example, Win7 on/dev/sda1

Then

1 $sudo fdisk-l

You can see where the win system is located, the starting bit 2048,end at 206847, and the sector information sectors of 1 * for the bytes.

1 sudo grub-install /dev/SDA  2sudo update-grub    3sudoddif=/dev/sda of=/dev/sda bs= count=1 seek= 2048 skip=206847

So on.
