I had installed opensuse in UEFI mode in my computer but having a legacy Windows so it did not appear in boot menu. Following a weird tutorial on the internet I dd the Windows partition of my sda.
dd if="some img" of=/dev/sdaX bs=4m
with X being the partition. The img was just some KB. I am aware, don't know whether it is true or not, that
dd starts writing from the first block of the device and therefore I think it just overwrote the partition information of the first KB of the partition block and therefore the system doesn't know what file system it is and therefore cannot mount it. But I don't know if
dd has wiped all the remaining data. Hence my question is whether there is a way to recover my data from that particular partition.
