To start, this is similar but not the same to Accidentally did dd /dev/sda because I restarted my computer.
I was making a bootable usb, and when I went to clear the partitions of the usb, I did:
dd if=/dev/zero of=/dev/sdb count=1 bs=4096
It turns out that sdb was my main hard drive for this particular boot (I don't know why, forgot to check before Destroying Data)
I was running dual boot with 15G in linux (part. 3), ~275G in Windows (part. 2).
I already shutdown my computer unknowingly. When I boot, I get ThinkPad splash screen, then:
Initializing Intel boot agent Initializing and establishing link... PXE-E61: Media test failure, check cable PXE-M0F: Exiting Intel boot agent.
Booting to a Kali live thumbdrive,
fdisk -l gives:
Disk /dev/sda: 298.1 GiB, 320072933376 bytes, 120845300 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
With no device list.
I would like to recover full working capability of my machine again, though I at least want my data if possible.
Let me know if any other information is needed. If you somehow haven't noticed yet, I'm a noob, so noob-friendly answers are appreciated. Thank you.
