Saya tidak sengaja menghapus sebagian besar tabel partisi windows saya pada laptop dual boot saya dan saya mencoba untuk memperbaiki / memulihkan tabel partisi yang salah.
Saya punya laptop dual boot: Ubuntu dan Windows. Grub masih berfungsi (saya bisa boot ke Ubuntu).
- Ubuntu 16.10 (termasuk partisi boot) terletak di
/dev/sdb - Windows 10 terletak di
/dev/sda.
Saya tidak sengaja menghapus sebagian besar tabel partisi windows saya dev/sda(kesalahan bodoh terjadi). Inilah yang tersisa menurut fdisk:
$ sudo fdisk -lu /dev/sda
Disk /dev/sda: 465,8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 6CAE9467-2FF5-4DB9-8E72-4321E9061C2A
Device Start End Sectors Size Type
/dev/sda2 923648 1128447 204800 100M EFI System
Saya masih dapat memilih Windows dari grub, tapi tentu saja sekarang saya baru saja (Bahasa Jerman untuk: Sembuh, sistem harus diperbaiki):
Dari /boot/grub/grub.cfgpada saya /dev/sdb:
menuentry 'Windows Boot Manager (on /dev/sda2)' --class windows --class os $menuentry_id_option 'osprober-efi-46A6-7D64' {
insmod part_gpt
insmod fat
set root='hd0,gpt2'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2 46A6-7D64
else
search --no-floppy --fs-uuid --set=root 46A6-7D64

P=Primary D=Deleted
Keys A: add partition, L: load backup, T: change type, P: list files,
Enter: to continue
NTFS, blocksize=4096, 471 MB / 450 MiB
Setelah melihat ke dalam setiap partisi menggunakan P: list files(perincian di bawah) tampaknya:
- partisi 1: Pemulihan. ok untuk disimpan?
- partisi 2: ok
- partisi 3: berisi konten windows10
- partisi 4: harus tetap dihapus (?)
- partisi 5: Pemulihan. boleh menghapus?
Pertanyaan saya:
- Haruskah saya memulihkan partisi 3 (menggunakan
L: load backup)? - Haruskah partisi 4 tetap dalam status
D(dihapus)? Sepertinya rusak pula. - Haruskah partisi 5 tetap dalam status
D(dihapus)? Ini berisi pemulihan, tetapi sudah ada pemulihan yang valid terletak di partisi 1. - Bagaimana cara memastikan bahwa
grubentri ke/dev/sda2titik ke lokasi yang benar?

Hint for advanced users. dmsetup may be used if you prefer to avoid to rewrite the partition table for the moment:
echo "0 921600 linear /dev/sda 2048" | dmsetup create test0
echo "0 204800 linear /dev/sda 923648" | dmsetup create test1
echo "0 974611379 linear /dev/sda 1161216" | dmsetup create test2
