Avoid third-party mirror sites, torrents, or unknown file-sharing links when downloading hypervisor software. Modified ISO files can contain malware, compromised security certificates, or backdoors that put your entire network infrastructure at risk.
VMware ESXi 7.0 is a foundational bare-metal hypervisor used globally for enterprise virtualization. While standard enterprise installations target fixed server hardware, creating a portable ESXi 7.0 environment offers unprecedented flexibility for system administrators, lab testers, and field engineers. A portable installation allows you to run ESXi directly from a bootable USB drive or a storage area network (SAN), transforming almost any compatible hardware into a temporary virtualization host without altering internal drives.
If your goal is to boot ESXi directly from the USB drive and save your hypervisor configurations, virtual switches, and password settings on that same drive, you must perform a self-installation. The Two-Drive Method

Enter the host machine's motherboard UEFI setup. Temporarily disable , or enable Legacy CSM Boot mode if your drive was compiled with an older partition map.
Follow the on-screen prompts. When asked to select a disk to install ESXi, carefully choose your second USB drive .

Obtain the latest version of the script from reputable community repositories (like GitHub).
To download the ESXi 7.0 ISO file, follow these steps:
Change the configuration directory to a standard mechanical drive or an SSD datastore instead of the USB partition, or configure remote Syslog management under Syslog.global.logHost to send logs over the network.

After downloading the ISO, it is a good practice to verify its integrity. The Broadcom portal often provides SHA256 checksums for each download. You can use a command-line tool like sha256sum on Linux or a third-party utility on Windows to calculate the hash of your downloaded file and compare it to the one on the website to ensure it hasn't been corrupted.
You cannot download a single "ESXi 70 portable.exe" file. However, you can download the and make it portable by installing it inside a VMware Workstation virtual machine . That VM file (the .vmx folder) is truly portable—you can copy it to a USB drive and run it on any computer that has Workstation installed.
