Installing anything without a working OS is a PITA. You can however install GRUB2 from LiveCD. This way it acomplishes "installing without having any OS on the disk" > 2.

Some of them can be easily told not to. Others are very insisting and need a heavy modifications not to. Nothing bootloader can do can prevent installer from overwriting it > 3. Whenever an OS can not be booted, the tool can recovery error. "can not be booted" is a very broad term and is not an actual error description. The range of possible problems is virtually limited only by the OS size. If OS was securely wiped you can't "recover" it other than by reinstalling or restoring from the backup. Both these methods are universal in the sense that they work even if the original computer falls into black hole. Both tasks are readily accomplished with archiver/backup tools rsp OS installer. > 4.

So in whole what you ask falls into categories of "already done", "done by separate tools" and "can be configured to but is suboptimal and so isn't a default". The only thing which isn't done is "universal OS recovery" since it would require to do the things which are as impossible as it gets (theoretically you can never really erase data according to second thermodynamical principle, but the data is so dispersed in environment that no modern observation method can recover it.) > -- > > *Best Regard > Du Hui* > Don't use HTML mail.
