0 I have googled a lot for this problem. I found this, but it didn't solve my problem. Other solutions suggest me to reinstall grub (run grub-install), which didn't help neither. Here is what I am doing: (my grub version is 2.02) I use grub2-mkrescue to make my X.iso I boot a VMWareWorkstation virtual machine, which has a 1.0GB SATA disk, from X.iso I install X.iso on disk, the details are: 3.1. erase /dev/sda in case there are old partitions on it: dd if=/dev/zero of=/dev/sda bs=1M count=1 3.2. Create 3 primary partitions on /dev/sda as dev/sda1,sda2,sda3 (the size is 100M, 30M and 70M), and toggle sda1 to be bootable Disk /dev/sda: 1024 MB, 1073741824 bytes, 2097152 sectors 130 cylinders, 255 heads, 63 sectors/track Units: sectors of 1 * 512 = 512 bytes Device Boot StartCHS EndCHS

Have any astronauts or cosmonauts died in space?

1 When I lived on the Space Coast I overheard gossip that one or more cosmonauts died in space. Is there any truth to this? I’m not asking about deaths from those disasters like Challenger, Columbia, or Apollo 1. I'm asking about death out in actual space. spaceflight share | improve this question edited 14 mins ago NonCreature0714 asked 1 hour ago NonCreature0714 NonCreature0714 146 5
