خرابی grub2 دیگه بوت نمیشه :(

[mojiz]

من سیستم رو از Lenny به squeeze آپگرید کردم و حالا موقع بوت grub ارور bad syntax میده و هیچ کدوم از کرنل هارو پیدا نمیکنه( منوی بوت هیچ کرنلی نداره)

دستورات زیر رو هم وارد میکنم خطا میده:

set root=hd(0,1)
linux /vmlinuz 
error: no such disk

کسی میتونه کمک کنه؟

با rescue کامپیوتر رو بوت کنید فایل grub.cnf را که در دایرکتوری /boot/grub هست دستی مقدار بدید .

[mojiz]

اسم فایل grub.cfg هست
تو این فایل یک سری چیز میز هست:

به نظر من خودت رو درگیر کدبازی و دستور نکن
راحت ترین راه برای بازیابی گراب2 در سیستم های دبیان-بیس استفاده از boot-repair هستش که رابط گرافیکی هم داره
