May na install na software yung tito ko, then nag reboot daw at biglang napunta sa grubfordos..

ngayon, di namin alam kung paano mag boot sa windows,, di ko alam tong grubfordos na to.

nag google search na ako, at nag come up ako sa command na chainloader (hd0,1) file not found ang response..

papano ba to?

TIA

try these commands in sequence sa command line ng grub

root (hd0,0)

chainloader  +1
==================================
Note: hd0 means first primary harddisk in the system
         0 means first partition in that hard disk
figure out na lang sa system mo kung nasaan ang windows boot partition mo

Hmm parang may nabanggit na neto si manay isabel.

Grubfor dos sa win7.

Patanong na lang sis drako kung native ba sa 7 ang grub?

actually di ako familiar sa grub4dos
yung alam ko konti ang grub na ginagamit sa linux
so I suppose pareho lang sila ng commands
as I read sa here [1], it is a DOS extension for GRUB which enables you
to setup and have the functionalities of GRUB in windows environment.
Malamang native sya sa Win 7.

wait na lang natin si sir hardcore misery kung successful sya sa bootup.

kung ayaw yung suggestion ni drako65, try mo ito:

press "C" sa grub menu para ma-edit yung command. type:

Code:

chainloader (hd0,0) /bootmgr


then press <enter>, then "B" to boot, then <enter> ulit.

substitute (hd0-3,0-9) for each try, e.g. (hd0,1) ... (hd1,1) ... (hd2,1) ... (hd2,2) ... and so on. pero dapat sa (hd0,0) pa lang mag boot na since sa 1st disk, 1st partition naka install ang windows.

Ganito lang pag remove nyan:

1. Put the Windows 7 installation/Upgrade disc in the disc drive, and then start the computer (set to boot from CD in BIOS).

2. Press a key when you are prompted.

3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.

4. Click Repair your computer.

5. Click the operating system that you want to repair (Windows 7 in this case), and then click Next.

6. In the System Recovery Options dialog box, click Command Prompt.

7. Once in the command prompt, type exactly Bootrec.exe /FixMbr and then press ENTER. You will see "operation completed successfully." (Doesnt even take a second. Dont be alarmed )

8. Reboot and set BIOS to boot from the HDD again.

GRUB will be overwritten in step 7 and Windows bootloader will once again take control of loading your OS(s).
