我看的文章都要先mount,但我用tab找不到
$ sudo mount /
/ /dev/sr0 /media/floppy0 /proc
硬要mount也不行
$ sudo mount /dev/sda2 /mnt
mount: you must specify the filesystem type
$ sudo mount -t ntfs /dev/sda2 /mnt
NTFS signature is missing.
Failed to mount '/dev/sda2': Invalid argument
The device '/dev/sda2' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
接下来我就卡住了,請問我該怎麽做?

以下是詳細過程
這台筆電是Asus U36S
我不確定出廠的硬碟分割是什麼樣
但我接手的時候是單純只有windows
兩個分割槽,系統與C槽(sda1, sda2)
由於要灌ubuntu所以我用內建的分割程式
http://www.techbang.com/posts/4023-windows-7-get-their-own-partition
但並沒有作格式化就直接重開安裝ubuntu了
安裝過程我選擇手動,選好新割出來的100G,只掛載/(也就是sda3)
接著就安裝了(開機裝在sda)
接著就遇到本文的問題
但試了推文的三個方法都沒改善,請大家再幫幫我吧,謝謝

我在cmd裡並沒有fdisk的指令,若你指的是linux的command
上文中有列出fdisk的細節
影片中的步驟我卡在對C碟的操作,顯示 磁碟區未包含可辨識的檔案系統
不過現在連missing os都看不到了,只剩游標在閃

我用bootrepair弄回grub了,現在能進ubuntu
在 /boot/grub/grub.cfg 加入
menuentry "Windows 7" {
set root=(hd0,msdos1)
chainloader +1
}
由grub進入win7的話,一樣是閃游標
改成msdos2也一樣

win的1,2都不行,testdisk也沒辦法,倆個partition都顯示
Cant open filesystem. Filesystem seems damaged.
看來是沒救了是嗎?
我比較好奇的是我哪一個步驟錯了,才剛灌ubuntu就不能mount(我猜這時候就無法辨識硬碟了)
是因為win有設開機密碼嗎?(不是登入的密碼,是loading前就要輸入的密碼)。
還是說不能灌在直接從C碟割出的分區呢?

是的,我三個都試過了,都無用。我猜當初應該是win有設磁碟加密的關係吧。
今天上班請同事接手,結果現在看到sda1,2被清空了,我想只剩重灌了。
目前卡在nb背面的product key是oem的,但官網又載不到oem的iso,關關難過關關沒過,Orz...
