host disk not visible

If you installed Ubuntu using the Wubi installer (that is, inside Windows, rather than alongisde Windows), then your Windows drive is called /host. If you cannot see it, go to File System in Nautilus (the Ubuntu file manager), and it will be in there. You do not have to edit anything. Furthermore, when people refer to "the hosts file" they are talking about something entirely unrelated to /host.

If you did not install Ubuntu using Wubi, or you did but those instructions don't work, then please open a Terminal window in the Ubuntu system and run this command:

df -h; mount; sudo fdisk -l

Please note that (1) the last letter of that command is a lower-case L, not an upper-case i, and (2) you may be prompted for your password, and as you enter it, you won't see any placeholder characters (like *), but that's OK (just type it in and press enter).

Then select all the text in the Terminal (Edit > Select All), copy it to the clipboard (Edit > Copy), and paste it here.
