how to quickstart the installation via putty having iso image of Linux 7 SW under temp director

Hi, need guidance here.
There is Linux 6 server. I have asked to install Linux 7 sw in it.
challenge here is we don't have access to server presently . I only have putty access from one place. I accessed the server and via winscp transferred the Linux 7 software. Now I am struck as I don't know how to start the installation process like this.
are they any specific commands which can trigger this iso file so that I can finish this installation. or its not possible to install like this ?
Thanks in advance,

Best regards,

I assume by Linux 6 server that you are probably running RHEL, CentOS or maybe Oracle. Unless the server has an IPMI or other similar interface I do not believe you can "trigger" a remote installation. To use an IPMI interface the installation media would have to be on a CD/DVD disc or USB.

grub 2 can boot an ISO but version 6 uses grub legacy which as far as I know can not and I do not know of any other way which does not require physical access. Once started the installation can be autonomous with a kickstart file.

It is possible to install grub2 but if something goes wrong you will not be able to connect to the server remotely again until you have physically access.

If you are running RHEL and have a subscription I might ask them to see if there are other ways.

You might need to provide more information i.e. if this is a VPS etc.
